net/mlx5e: Reset RQ doorbell counter before moving RQ state from RST to RDY

Browse source 
commit 5ee090ed0d upstream.

Initialize RQ doorbell counters to zero prior to moving an RQ from RST
to RDY state. Per HW spec, when RQ is back to RDY state, the descriptor
ID on the completion is reset. The doorbell record must comply.
