SVN rev 179554 on 2008-06-05 09:15:47Z by kib
When devfs_allocv() committed to create new vnode, since de_vnode is NULL,
the dm_lock is held while the newly allocated vnode is locked. Since no
other threads may try to lock the new vnode yet, the LOR there cannot
result in the deadlock.
Shut down the witness warning to note this fact.
