wifi: ath12k: Refactor Rx status TLV parsing procedure argument

Currently, ath12k_dp_mon_rx_parse_status_tlv() takes the TLV tag, TLV data
and TLV userid as separate arguments from the caller. In the future, the
TLV length will be needed for parsing the EHT TLV tag. Therefore, instead
of increasing the number of arguments, pass the TLV header and retrieve the
necessary fields from the TLV header itself.
