Firmware sends NAN log events to driver and these are logged
with info level to capture complete NAN state machine logs in kmsg.
Currently, these events are received/processed in soft IRQ context
and causes performance issues as logs introduce delays. Move the
event registration to RX_WORK context to avoid delays.
