net: ravb: Disable IP header TX checksum offloading

Browse Source 
For IPv4 packets, the header checksum will always be calculated in software
in the TX path (Documentation/networking/checksum-offloads.rst says "No
offloading of the IP header checksum is performed; it is always done in
software.") so there is no advantage in asking the hardware to also
calculate this checksum.
