nvme-multipath: fix io accounting on failover
[ Upstream commit a2e4c5f5f68dbd206f132bc709b98dea64afc3b8 ]
There are io stats accounting that needs to be handled, so don't call
blk_mq_end_request() directly. Use the existing nvme_end_req() helper
that already handles everything.
Fixes: d4d957b53d91ee ("nvme-multipath: support io stats on the mpath device")
