amiflop,ataflop,xd,mg_disk: clean up unnecessary stuff from block drivers
rq_data_dir() can only be READ or WRITE and rq->sector and nr_sectors
are always automatically updated after partial request completion.
Don't worry about rq_data_dir() not being either READ or WRITE or
manually update sector and nr_sectors.
[ Impact: cleanup ]
