[PATCH v3 06/12] ath11k: remove usage quota while processing rx packets

[P Praneesh <ppranees@xxxxxxxxxxxxxx>]

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.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01695-QCAHKSWPL_SILICONZ-1
