i40e/i40evf: Remove unused hardware receive descriptor code
The hardware supports a 16 byte descriptor for receive, but the
driver was never using it in production. There was no performance
benefit to the real driver of 16 byte descriptors, so drop a whole
lot of complexity while getting rid of the code.
Also since the previous patch made us use no-split mode all the
time, drop any support in the driver for any other value in dtype
and assume it is always zero (aka no-split).
Hooray for code removal!
