[PATCH] autofs4 doesn't expire

[spam@streefland.xs4all.nl (Dick Streefland)]

In linux-2.6.0-test1, lookup_mnt() was changed to increment the ref
count of the returned vfsmount struct. This breaks expiration of
autofs4 mounts, because lookup_mnt() is called in check_vfsmnt()
without decrementing the ref count afterwards. The following patch
fixes this:
