[PATCH ath-next] wifi: ath12k: Clear auth flag only for actual association in security mode

From: Thiraviyam Mariyappan <thiraviyam.mariyappan at oss.qualcomm.com>

When setting a new bitrate, WMI peer association command is sent from
the host without the peer authentication bit set in peer_flags for
security mode, which causes ping failure.

The firmware handles peer_flags when the client is associating, as the
peer authentication bit in peer_flags is set after the key exchange.
When the WMI peer association command is sent from the host to update
the new bitrate for an associated STA, the firmware expects the WMI
peer authentication bit to be set in peer_flags.

Fix this issue by ensuring that the WMI peer auth bit is set in
peer_flags in WMI peer association command when updating the new
bitrate.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
