wifi: ath12k: Remove unused scan_flags from struct ath12k_wmi_scan_req_arg

As we did for ath11k lets remove the unused scan_flags from struct
ath12k_wmi_scan_req_arg. This will prevent us from using out of sync values
between WMI_SCAN_XXX & scan_f_xxx bitfield.
While at it remove the underlying wrapping struct/union construct as it serves
no purpose anymore.
