fix old umount_tree() breakage
Expiry-related code calls umount_tree() several times with the same list to collect vfsmounts to. Which is fine, except that umount_tree() implicitly assumed that the list would be empty on each call - it moves the victims over there and then iterates through the list kicking them out. It's *almost* idempotent, so everything nearly worked. However, mnt->ghosts handling (and thus expirability checks) had been broken - that part was not idempotent... The fix is trivial - use local temporary list, splice it to the the collector list when we are through. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
