Subject: [PATCH] wcn36xx: Increase number of TX retries

Git-commit: 1c20560607e6e142af76b9bd57e275b9053958a1

References: git-fixes

Patch-mainline: v5.10-rc1

Increase the short/long retry limit to 15 in order to impove TX

robustness in noisy/busy environment. 15 is the default value

defined in the downstream driver. Observed number of ack timeout

is reduced with this change.
