wifi: ath11k: fix firmware assert during bandwidth change for peer sta
Currently, ath11k sends peer assoc command for each peer to
firmware when bandwidth changes. Peer assoc command is a
bulky command and if many clients are connected, this could
lead to firmware buffer getting overflowed leading to a firmware
assert.
However, during bandwidth change, only phymode and bandwidth
also can be updated by WMI set peer param command. This makes
the overall command light when compared to peer assoc and for
multi-client cases, firmware buffer overflow also does not
occur.
Remove sending peer assoc command during sta bandwidth change
and instead add sending WMI set peer param command for phymode
and bandwidth.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1
