net: xilinx: axienet: Relax partial rx checksum checks

Browse Source 
The partial rx checksum feature computes a checksum over the entire
packet, regardless of the L3 protocol. Remove the check for IPv4.
Additionally, testing with csum.py (from kselftests) shows no anomalies
with 64-byte packets, so we can remove that check as well.
