nvme-tcp: fix bogus request completion when failing to send AER

Browse Source 
commit 63573807b2 upstream.

AER is not backed by a real request, hence we should not incorrectly
assume that when failing to send a nvme command, it is a normal request
but rather check if this is an aer and if so complete the aer (similar
to the normal completion path).
