qcacmn: Add reason codes to report various connect fail

The connection process fails for several reasons and the status codes
defined in IEEE802.11 specification doesn't 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 driver/firmware to report various
additional reason codes for connection failures.
