[SECURITY PATCH 3/8] net/net: Unregister net_set_vlan command on unload

From: Thomas Frauendorfer | Miray Software <[email protected]>

The commit 954c48b9c (net/net: Add net_set_vlan command) added command
net_set_vlan to the net module. Unfortunately the commit only added the
grub_register_command() call on module load but missed the
grub_unregister_command() on unload. Let's fix this.

Fixes: CVE-2025-54770
Fixes: 954c48b9c (net/net: Add net_set_vlan command)
