bcache: fix I/O accounting leak in detached_dev_do_request
[ Upstream commit 4da7c5c3ec34d839bba6e035c3d05c447a2f9d4f ]
When a bcache device is detached, discard requests are completed
immediately. However, the I/O accounting started in
cached_dev_make_request() is not ended, leading to 100% disk
utilization reports in iostat. Add the missing bio_end_io_acct() call.
