Log Message:
Check `b_dev' field in bdwrite() before using it as an index into bdevsw[].
`b_dev' value of NODEV happens and is normal if the buffer is on its way
to the underlying device strategy function for the first time.

Also, MFS sillily uses a major device number (255) which cannot be used
to index bdevsw[]. Check marked with XXXs.
