eventdev: fix missing update to Rx adaper WRR position

Browse Source 
After dequeuing Rx packets and enqueueing them to the
temporary buffer towards eventdev, the packet Rx loop exits
if the temporary buffer is full but the current WRR position
is not saved.

Save away the current value of the WRR position, so packets
are dequeued from the correct Rx queue in the next invocation.
