qcacld-3.0: Refine the RSSI Threshold Breach callback API

The RSSI Threshold Breach callback currently specifies a void pointer
for the context. In the case of this API the context is actually known
to be an HDD handle, so update the API to explicitly use this
type. This will allow the compiler to verify that the correct type of
parameter is being passed.
