Attilio Rao a3c14ce5d9 namei() can call underlying nfs_readlink() passing a struct uio pointer ... owned by a NULL owner. This will lead consequent VOP_ISLOCKED() present into nfs_upgrade_vnlock() to panic as it only acquire curthread now. Fix nfs_upgrade_vnlock() and nfs_downgrade_vnlock() in order to not use more the struct thread pointer passed as argument (as it is really nomore required there as vn_lock() and VOP_UNLOCK doesn't get the lock more). Using curthread, in place, doesn't get ambiguity as LK_EXCLOTHER should be handled as a "not locked" request by both functions.
