[PATCH net v2 2/2] net: lan966x: Fix sleep in atomic context when updating MAC table

[Horatiu Vultur <horatiu.vultur@microchip.com>]

The function lan966x_mac_wait_for_completion is used to poll the status
of the MAC table using the function readx_poll_timeout. The problem with
this function is that is called also from atomic context. Therefore
update the function to use readx_poll_timeout_atomic.
