[PATCH v1 1/1] block: Add handling for zone append command in blk_complete_request

[Pankaj Raghav <p.raghav@xxxxxxxxxxx>]

Zone append command needs special handling to update the bi_sector
field in the bio struct with the actual position of the data in the
device. It is stored in __sector field of the request struct.

Fixes: 5581a5ddfe8d ("block: add completion handler for fast path")
