Introduce QCA_NL80211_VENDOR_SUBCMD_HANG

This is an event indicating to the user space that the driver has
detected an internal failure. The driver is expected to recover from
such a failure automatically, e.g., by resetting the device. This event
carries the information indicating the reason that triggered this
detection.
