netdev-dpdk: Remove workarounds for fixed checksum bugs.

net/tap fixes were merged as part of
v21.11.6/v22.11.4/v23.11 DPDK LTS versions.

A net/txgbe fix was merged as part of
v21.11.9/v22.11.7/v23.11.3/v24.11 DPDK LTS versions.

We can remove the capability filtering workarounds now that
OVS main branch requires at least v24.11.
