ath11k: set WMI_PEER_40MHZ while peer assoc for 6 GHz
[ Upstream commit 1cb747192de2edb7e55920af8c458e4792908486 ]
When station connect to AP of 6 GHz with 40 MHz bandwidth, the TX is
always stay 20 MHz, it is because the flag WMI_PEER_40MHZ is not set
while peer assoc. Add the flag if remote peer is 40 MHz bandwidth.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2
