[PATCH 0/2] selftests: ublk: fix the fault_inject delay

[Qiliang Yuan]

The delay set by --delay_us on the fault_inject target is lost in two
ways. Its timespec is read after it has gone out of scope, which makes
generic_06 fail, and any other completion on the ring ends it early when
more than one I/O is in flight. Patch 1 keeps the timespec alive until
the SQE is submitted, and patch 2 makes the delay a pure timeout.

With both patches, a 1 s delay holds every I/O for 1.000 s at queue
depth 4.
