Add QCA interface for driver to report various connect fail reason codes

The connection process fails for several reasons and the status codes
defined in IEEE Std 802.11 do not cover the locally generated reason
codes. Add an attribute to QCA_NL80211_VENDOR_SUBCMD_GET_STA_INFO vendor
sub command which can be used by the driver/firmware to report various
additional reason codes for connection failures.
