qcacld-3.0: Fix CDS layering violation in hdd_context_create()

Currently hdd_context_create() directly dereferences the global CDS
context pointer in order to save a pointer to the HDD context. This is
a layering violation. Instead update cds_set_context() to handle the
HDD context, and call that from hdd_context_create() to save the
pointer to the HDD context.
