MFC r232959 and r232960:

Prevent tmpfs_rename() deadlock in a way similar to UFS. Unlock
vnodes and try to lock them one by one. Relookup fvp and tvp.

Don't enforce LK_RETRY to get existing vnode in tmpfs_alloc_vp().
Doomed vnode is hardly of any use here, besides all callers handle
error case. vfs_hash_get() does the same. Don't mess with vnode
holdcount, vget() takes care of it already.
