Please change the subject to "landlock: Allow FS topology changes for
domains without such rule type" to be consistent with the documentation.

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.

Remove unnecessary inlining.
