qcacmn: Introduce QCA_NL80211_VENDOR_SUBCMD_HANG
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.
