Log Message:
Pull up following revision(s) (requested by pooka in ticket #413):
        sys/ufs/ufs/ufs_inode.c: revision 1.77
Break hold-and-wait which happens in ufs_balloc_range() when we
have pages busied and are trying to get the genfs node lock.
This causes a lock order reversal described in PR kern/40389.
This is not a proper fix and only a workaround for NetBSD 5.0.
problem first reported by simonb, patch tested by rmind
