net: enetc: update UDP checksum when updating originTimestamp field
There is an issue with one-step timestamp based on UDP/IP. The peer will
discard the sync packet because of the wrong UDP checksum. For ENETC v1,
the software needs to update the UDP checksum when updating the
originTimestamp field, so that the hardware can correctly update the UDP
checksum when updating the correction field. Otherwise, the UDP checksum
in the sync packet will be wrong.
Fixes: 7294380c5211 ("enetc: support PTP Sync packet one-step timestamping")
