IB/hfi1: Fix PIO wakeup timing hole
There is a timing hole if there had been greater than
PIO_WAIT_BATCH_SIZE waiters. This code will dispatch the first
batch but leave the others in the queue. If the restarted waiters
don't in turn wait on a buffer, there is a hang.
Fix by forcing a return when the QP queue is non-empty.
