cnss2: Initialize completion event at right place

CNSS2 registers PCI event callback for wake irq from
PCI driver. When callback is called CNSS2 completes
wake_event to notify the waiting threads. Currently,
initialization of wake_event completion is done after
PCI event callback registration causing issue when
PCI even callback for wake irq is called before wake_event
completion could initialize.

Initialize wake_event completion before PCIe event callback
registration.
