Subject: [PATCH 5.19 254/717] wifi: ath11k: Include STA_KEEPALIVE_ARP_RESPONSE TLV header by default

From: Baochen Qiang <quic_bqiang@...cinc.com>

[ Upstream commit b7b6f86149a7e06269d61a7a5206360f5b642f80 ]

In current code STA_KEEPALIVE_ARP_RESPONSE TLV header is included only
when ARP method is used, this causes firmware always to crash when wowlan
is enabled because firmware needs it to be present no matter ARP method
is used or not.

Fix this issue by including STA_KEEPALIVE_ARP_RESPONSE TLV header by
default.

Also fix below typo:
  s/WMI_TAG_STA_KEEPALVE_ARP_RESPONSE/WMI_TAG_STA_KEEPALIVE_ARP_RESPONSE/

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3

Fixes: 0f84a156aa3b ("ath11k: Handle keepalive during WoWLAN suspend and resume")
