[ Upstream commit d65ab7c0e0b92056754185d3f6925d7318730e94 ]
It's been a while that the firmware uses LONG_GROUP by default and not LEGACY_GROUP. Until now the firmware wrongly advertise the WOWLAN_GET_STATUS command's version with LEGACY_GROUP, but it is now being fixed. In order to support both firmwares, first try to get the version number of the command with the LONG_GROUP and if the firmware didn't advertise the command version with LONG_GROUP, try to get the command version with LEGACY_GROUP.
