Subject: blk-mq: remove the done argument to blk_execute_rq_nowait
Git-commit: e2e530867245d051dc7800b0d07193b3e581f5b9
Patch-mainline: v5.19-rc1
References: git-fixes
Let the caller set it together with the end_io_data instead of passing
a pointless argument. Note the the target code did in fact already
set it and then just overrode it again by calling blk_execute_rq_nowait.
