Fix bug in brelse() regarding redirtying buffers on B_ERROR. brelse()

    improperly ignored the B_INVAL flag when acting on the B_ERROR.
    If both B_INVAL and B_ERROR are set the buffer is typically out of the
    underlying device's block range and must be destroyed.  If only B_ERROR
    is set (for a write), a write error occured and operation remains as it
    was before:  the buffer must be redirtied to avoid corrupting the
    filesystem state.
