qcacld-3.0: Refine the Thermal Level callback API

The Thermal Level 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.
