autofs - dont hold spin lock over direct mount expire
Commit 7cbdb4a286 altered the autofs indirect mount expire to
not hold a spin lock during the expire check.
The direct mount expire needs the same treatment because to
make autofs expires namespace aware may_umount_tree() needs to
to use a similar method to may_umount() when checking if a mount
tree is in use.
This means may_umount_tree() will end up taking the namespace_sem
for the check so the autofs direct mount expire won't be allowed
to hold a spin lock over the check.
