qcacld-3.0: Remove wlan_sap_set_pre_cac_status() handle param

Function wlan_sap_set_pre_cac_status() currently takes as one
parameter a tHalHandle handle.  This handle is converted into a MAC
context pointer. That MAC context pointer is then tested for NULL but
is otherwise unused.  Since the MAC context, and hence the handle, are
unnecessary, remove them.

This is part of an ongoing campaign to remove or replace all instances
of tHalHandle.
