block: reorder request completion functions
Reorder request completion functions such that
* All request completion functions are located together.
* Functions which are used by only one caller is put right above the
caller.
* end_request() is put after other completion functions but before
blk_update_request().
This change is for completion function cleanup which will follow.
[ Impact: cleanup, code reorganization ]
