Summary
nbd: fix race between timeout and normal completion
Details

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

nbd: fix race between timeout and normal completion

If request timetout is handled by nbdrequeuecmd(), normal completion has to be stopped for avoiding to complete this requeued request, other use-after-free can be triggered.

Fix the race by clearing NBDCMDINFLIGHT in nbdrequeuecmd(), meantime make sure that cmd->lock is grabbed for clearing the flag and the requeue.
