Instead of passing around a bitmap of ops and flags, the
next patches separate it into a op field and a flags field.

This patch prepares submit_bio_wait callers for the next
patches that split bi_rw into a operation and flags field.
Instead of passing in a bitmap with both the operation and
flags mixed in, the callers now pass them in seperately.

This patch adds definitions for request/bio operations which
will be used in the next patches.
In the initial patches the REQ_OPs match the REQ ones for compat reasons
