ath11k_nss: Improve NSS event callback handling

Browse Source 
Improve NSS event callback ihandling for better clarity and type safety

This patch modifies ath11k_nss_wifili_event_receive to take a context parameter
, enhancing code clarity by explicitly passing the ath11k_base.

A wrapper function, ath11k_nss_wifili_ext_callback_wrapper, retrieves
the ath11k_base from the net_device's private data, ensuring correct
context handling.
