[PATCH] fuse: fix spurious BUG
Fix a spurious BUG in an unlikely race, where at least three parallel lookups
return the same inode, but with different file type. This has not yet been
observed in real life.
Allowing unlimited retries could delay fuse_iget() indefinitely, but this is
really for the broken userspace filesystem to worry about.
