nvme: zero request->submit_tick in allocation

Browse Source 
Request may be submitted several times via nvme_qpair_submit_request
function, such as request in queued_req queue being re-submitted.

With enabling timeout feature, nvme_qpair_submit_request compares
request->submit_tick to zero to check if this is the first submission
for this request. If true, record submit_tick for this reuqest.

So request->submit_tick needs to be set zero in allocation.
