drm/i915/guc: Check if expecting reply before decrementing outstanding_submission_g2h
When sending a H2G message where a reply is expected in
guc_submission_send_busy_loop(), outstanding_submission_g2h is
incremented before the send. However, if there is an error sending the
message, outstanding_submission_g2h is decremented without checking if a
reply is expected.
Therefore, check if reply is expected when there is a failure before
decrementing outstanding_submission_g2h.
