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

[Jouni Malinen]

From: P Praneesh <ppranees at codeaurora.org>

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 remove use of the 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
