If VPP crashes, the system loads without hugepages
Initial config:
```
set interfaces ethernet eth1 address '192.0.2.1/30'
set interfaces ethernet eth1 description 'LAN'
set interfaces ethernet eth1 vif 11 address '10.0.11.1/30'
set interfaces ethernet eth1 vif 12 address '10.0.12.1/30'
set interfaces ethernet eth1 vif 13 address '10.0.13.1/30'
set interfaces ethernet eth1 vif 14 address '10.0.14.1/30'
set interfaces ethernet eth1 vif 15 address '10.0.15.1/30'
set interfaces ethernet eth1 vif 16 address '10.0.16.1/30'
set interfaces ethernet eth1 vif 17 address '10.0.17.1/30'
set interfaces ethernet eth1 vif 18 address '10.0.18.1/30'
set system option kernel disable-mitigations
set system option kernel memory hugepage-size 2M hugepage-count '1650'
set vpp settings interface eth1 dpdk-options promisc
set vpp settings interface eth1 driver 'dpdk'
set vpp settings lcp netlink batch-delay-ms '10'
set vpp settings lcp netlink batch-size '1024'
set vpp settings lcp netlink rx-buffer-size '8388608'
set vpp settings memory main-heap-page-size '2M'
set vpp settings memory main-heap-size '3G'
set vpp settings statseg size '128M'
set vpp settings unix poll-sleep-usec '222'
```
All works fine and we see required kernel options:
```
vyos@r14:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/2025.07.22-0021-rolling/vmlinuz boot=live rootdelay=5 noautologin net.ifnames=0 biosdevname=0 vyos-union=/boot/2025.07.22-0021-rolling mitigations=off hugepagesz=2M hugepages=1650 console=tty0
vyos@r14:~$
```
Crash VPP, I sed 8 Full BGP tables, boug could be produced via `kill` (several times)
```
vyos@r14:~$ sudo kill -9 `pidof vpp`
vyos@r14:~$
vyos@r14:~$ sudo pidof vpp
vyos@r14:~$ sudo pidof vpp
vyos@r14:~$
vyos@r14:~$
vyos@r14:~$ sudo pidof vppConnection to 192.168.122.14 closed by remote host.
Connection to 192.168.122.14 closed.
sever@sever:~$
```
Reboot the system and it loads without VPP and `kernel-options hugepages` in `/proc/cmdline`
```
vyos@r14:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/2025.07.22-0021-rolling/vmlinuz boot=live rootdelay=5 noautologin net.ifnames=0 biosdevname=0 vyos-union=/boot/2025.07.22-0021-rolling console=tty0
vyos@r14:~$
```
Check after crash after reboot:
```
vyos@r14:~$ conf
WARNING: There was a config error on boot: saving the configuration now could overwrite data.

Not enough free hugepage memory to start VPP: available: 0.0 GB,
required: 3.2 GB. Please add kernel memory options for HugePages and

If we reboot again, the system will load with VPP and kernel options.
