Unionfs: prevent deadlock with branch-management code.
Don't grab the superblock read-lock in unionfs_permission, which prevents a
deadlock with the branch-management "add branch" code (which grabbed the
write lock). It is safe to not grab the read lock here, because even with
branch management taking place, there is no chance that unionfs_permission,
or anything it calls, will use stale branch information.
