block: blk_rq_[cur_]_{sectors|bytes}() usage cleanup
With the previous changes, the followings are now guaranteed for all
requests in any valid state.
* blk_rq_sectors() == blk_rq_bytes() >> 9
* blk_rq_cur_sectors() == blk_rq_cur_bytes() >> 9
Clean up accessor usages. Notable changes are
* nbd,i2o_block: end_all used instead of explicit byte count
* scsi_lib: unnecessary conditional on request type removed
[ Impact: cleanup ]
