From: Harshitha Prem <quic_hprem@xxxxxxxxxxx>
Add support to process WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT
service bit. If this service bit is set by firmware, then it expects
host to set rx_peer_meta_data_ver in wmi_resource_config's flags2
with value 3 for QCN9274 to indicate as V1B meta version. If this is
not set firmware crash is seen during peer addition.
Hence, if WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit
is set by firmware, set correct peer metadata version to avoid
firmware crash.
