nvme/perf: fix the execption case for NVMe qpair polling.

Browse Source 
If do not do that, we will continue polling. And checked
the exceptional handling of aio_check_io, it will just exit.
So we add such case, thus we shall not poll the qpair again.

This is especially useful when we use perf to test against
NVMe-oF target.
