Log:
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.
