Allow mount point and root directory changes when there is no filesystem
rule tied to the current Landlock domain.  This doesn't change anything
for now because a domain must have at least a (filesystem) rule, but
this will change when other rule types will come.  For instance, a
domain only restricting the network should have no impact on filesystem
restrictions.

Add a new get_current_fs_domain() helper to quickly check filesystem
rule existence for all filesystem LSM hooks.

    Ok. I got it.
    Do I need also to add a new network helper:
    like landlock_get_raw_net_access_mask?

A get_raw helper would not be useful if there is not network access 
initially denied (like for FS_REFER).
