Chunwei Chen 29572ccdef Fix empty xattr dir causing lockup 
During zfs_rmnode on a xattr dir, if the system crash just after
dmu_free_long_range, we would get empty xattr dir in delete queue. This would
cause blkid=0 be passed into zap_get_leaf_byblk when doing zfs_purgedir during
mount, and would try to do rw_enter on a wrong structure and cause system
lockup.

We fix this by returning ENOENT when blkid is zero in zap_get_leaf_byblk.
