qed: replace is_write with flags field

Per-request attributes like read/write are currently implemented as bool
fields in the QEDAIOCB struct.  This becomes unwiedly as the number of
attributes grows.  For example, the qed_aio_setup() function would have
to take multiple bool arguments and at call sites it would be hard to
distinguish the meaning of each bool.

Instead use a flags field with bitmask constants.  This will be used
when zero write support is added.
