swim: clean up request completion paths 

swim curiously tries to update request parameters before calling
__blk_end_request() when __blk_end_request() will do it anyway and
unnecessarily checks whether current_nr_sectors is zero right after
fetching.

Drop unnecessary stuff and use standard block layer mechanisms.

[ Impact: cleanup ]
