ath11k: remove usage quota while processing rx packets

Browse Source 
The usage of quota variable inside ath11k_dp_rx_process_received_packets()
is redundant. Since we would queue only max packets to the list before
calling this function so it would never exceed quota. Hence removing
usage of quota variable.
