fs: namespace: allow mounting blockdevices without extra options
ve_devmnt_process will iterate over all device-mounts of the current
ve namespace and will bounce the mount in case opts is a non NULL
pointer. Change the behavior to allow it.
Our goal is:
- device cgroup ebpf filters will filter which devices are allowed to be
mounted, and which not.
- ve.mount_opts will be used as a filter of which mount options are
allowed. It shouldn't deny mounting when no options are passed but it
should deny in case some option is passed that is not explicitly
allowed.
Feature: ve: ve generic structures
