nvme: fix multipath crash caused by flush request when blktrace is enabled

5.5 MediumFix available

In the Linux kernel, the following vulnerability has been resolved:

nvme: fix multipath crash caused by flush request when blktrace is enabled

The flush request initialized by blk_kick_flush has NULL bio, and it may be dealt with nvme_end_req during io completion. When blktrace is enabled, nvme_trace_bio_complete with multipath activated trying to access NULL pointer bio from flush request results in the following crash:
