block: rename bio bi_rw to bi_opf

Browse Source 
Since commit 63a4cc2486, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

@ -269,7 +269,7 @@ Arjan's proposed request priority scheme allows higher levels some broad
requests which haven't aged too much on the queue. Potentially this priority
could even be exposed to applications in some manner, providing higher level
tunability. Time based aging avoids starvation of lower priority
requests. Some bits in the bi_rw flags field in the bio structure are
requests. Some bits in the bi_opf flags field in the bio structure are
intended to be used for this priority information.
