[ Upstream commit 588b45c88ae130fe373a8c50edaf54735c3f4fe3 ]

Firmware can trigger a missed beacon indication, this is not the same as a
lost signal.

Flag to Linux the missed beacon and let the WiFi stack decide for itself if
the link is up or down by sending its own probe to determine this.

We should only be signalling the link is lost when the firmware indicates
