amd-xgbe: Fix to ensure dependent features are toggled with RX checksum offload

commit f04dd30f1bef1ed2e74a4050af6e5e5e3869bac3 upstream.

According to the XGMAC specification, enabling features such as Layer 3
and Layer 4 Packet Filtering, Split Header and Virtualized Network support
automatically selects the IPC Full Checksum Offload Engine on the receive
side.

When RX checksum offload is disabled, these dependent features must also
be disabled to prevent abnormal behavior caused by mismatched feature
dependencies.

Ensure that toggling RX checksum offload (disabling or enabling) properly
disables or enables all dependent features, maintaining consistent and
expected behavior in the network device.
