qcacld-3.0: Add db2dbm conversion check

Browse Source 
When WMI_IFACE_LINK_STATS_EVENTID is received, WMA layer should
check FW service bit to confirm if HW db2dbm conversion is
enabled or not, or the final results indicated to HDD layer
will be inaccurate.

Add FW service bit checking to make sure db2dbm conversion is
done by driver when HW doesn't support it.
