xfs_growfs manpage clearly states that the filesystem must
be mounted to be grown. Current behavior allows xfs_growfs
to proceed if the filesystem /containing/ the path
of the desired target is mounted. This is not the specified
behavior. Instead, also check the targeted fs argument against
the entry found in the fstable lookup. Unless the targeted
fs is actually mounted, reject the command.
