[PATCH v3] kni: update kernel API to receive packets

[Gagandeep Singh <g.singh@nxp.com>]

API 'netif_rx_ni()' has been removed in kernel with commit:
baebdf48c3600 ("net: dev: Makes sure netif_rx() can be invoked in any context.")

The API netif_rx() can be used for any context to receive packets
from device drivers.

This patch replaces the API netif_rx_ni() with netif_rx() for
kernel version 5.18 and above.

Signed-off-by: Gagandeep Singh <g.singh@nxp.com>

v2 Change-log:
Added a #if for kernel version 5.18 and above for API change.

v3 Change-log:
Moved #if of kernel check to compat.h
