net: ethernet: microchip: lan743x: Fix skb allocation failure

commit e8684db191e4164f3f5f3ad7dec04a6734c25f1c upstream.

The driver allocates skb during ndo_open with GFP_ATOMIC which has high chance of failure when there are multiple instances.
GFP_KERNEL is enough while open and use GFP_ATOMIC only from interrupt context.

Fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver")
