wcnss: Trigger WCNSS driver on first open 



WCNSS driver requires a trigger followed by an open, this is to support
the trigger from an external script. However, startup scripts are no
more supported; and wcnss service should always trigger this driver. So
the first open to this driver should also trigger the driver.
