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 (that is from wcnss service), should also
trigger the driver.
