net:wireless:cnss2: Fix driver loading failure

When driver loading and registering to cnss,
the interruptible wait in cnss_driver_event_post
could be woken up by signal. In this driver
register failure case, the __hdd_module_init
will release all the driver resource.
But the cnss_driver_event_work is still probing
the driver normally in the same time. The driver
state mismatch will cause crash.

Fixed by using non interruptible wait for driver
register
