[PATCH 12/18] bgscan_simple: Verify if notified signal is above or below threshold

[andrei.otcheretianski at intel.com]

From: Avraham Stern <avraham.stern at intel.com>

When receiving signal change notification check if the reported
signal is above or below the signal threshold.
Although the event data includes this information, the threshold
configured to the driver might have changed.
