This patch converts cpqarray to use blk_end_request().
cpqarray is a little bit different from "normal" drivers.
cpqarray directly calls bio_endio() and disk_stat_add()
when completing request. But those can be replaced with
__end_that_request_first().
After the replacement, request completion procedures of
those drivers become like the following:
o end_that_request_first()
o add_disk_randomness()
o end_that_request_last()
This can be converted to blk_end_request() by following
the rule (b) mentioned in the patch subject
"[PATCH 01/27] blk_end_request: add new request completion interface".
