When a vring is started the back-end must look for available vq buffers
and process them. This scenario can happen if the back-end is stopped
with unprocessed available buffers and then started again.
The inflight I/O tracking code already did this, but it should also be
done when inflight I/O tracking is not enabled.
Move the code and make it robust in case of EINTR or EAGAIN.
