Naga Harish K S V 81da8a5ff4 eventdev/eth_rx: fix WRR buffer overrun 
When a poll queue is removed from a rx_adapter instance, the WRR poll
array is recomputed. The wrr array length is reduced in this case. The
next wrr position to poll is stored in wrr_pos variable of rx_adapter
instance. This wrr_pos can become invalid in some cases after wrr is
recomputed. Using this variable to get the next queue and device pair
may leed to wrr buffer overruns.

Resetting the wrr_pos to zero after recomputation of wrr array fixes
the buffer overrun issue.
