qcacmn: Remove unnecessary NULL check before dereferenced
Pointer is dereferenced after it was positively checked for NULL.
Since the handle should already check for null when we call
cds_get_context, when we recieve the handle as an argument, we should
know that it is not null. So remove the unnecessary null check here.
