qcacld-3.0: Return valid firmware version to upper layer

When upper layer requests for firmware version using vendor command,
QCA_NL80211_VENDOR_SUBCMD_GET_WIFI_INFO, after parsing vendor command
attributes to tb_vendor structure, Host is checking for DRIVER version
attribute(which will be invalid in case upper layer sends Firmware
version attribute) leading Host to send firmware version as NULL.

Check for firmware version attribute so that valid firmware version
is returned to upper layer.
