[PATCH] ath11k: Update tx descriptor search index properly

[Karthikeyan Periyasamy]

Tx descriptor search index field should be updated with hw peer id
and not by AST Hash. Incorrect search index causes throughput degradation
in all the platforms. so updated the search index field with hw peer id,
which is a common change applicable for all the platforms.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01492-QCAHKSWPL_SILICONZ-1

Could you be more details under what conditions you observed the 
throughput degradation?
