  netdev-dpdk: Remove Rx checksum reconfigure.

Rx checksum offload is enabled by default on DPDK physical NICs
where available, with reconfiguration through
options:rx-checksum-offload. However, changing rx-checksum-offload
did not result in a reconfiguration of the NIC and wrong status is
reported for it.

As there seems to be diminishing reasons why a user would want
to disable Rx checksum offload, just remove the broken reconfiguration
option.

  netdev-dpdk: Log Rx checksum offload not supported.

Rx checksum offload is enabled by default on DPDK NICs where
supported. Previously Rx checksum offload not supported was
logged only once. It meant that if multiple NICs did not
support Rx checksum offload, it was only reported for the
first NIC configured.
