qcacmn: Add shared print_ctrl_obj for qdf_trace_msg

At this point lot of Win code already uses QDF_TRACE macro. It will be
difficult to translate QDF_TRACE to qdf_trace_msg unless all the modules
(already using QDF_TRACE) make changes to use the qdf_print_ctrl
framework. Until that happens, we can have a shared object temporarily
so that wlan_log_to_user and hence user space logging of messages can be
in place
