upon daemonizing, wait on mtab update to terminate in parent
This fixes the race in between the mtab update attempts of mount and umount when we do a lazy umount right after mounting, in order to hide the given fs instance; yet this way we still avoid the deadlock of the fs and mount which we can hit if we wait unconditionally for the mtab update to terminate (cf. bz #511).
