net/i40e: fix SFP X722 with FW4.16

When NVM API version is 1.7 or above adminq operation to set TPID is
set as supported. This cause using adminq instead of registers.

For SFP X722 FW4.16, reported NVM API version is 1.8, and this cause
adminq operation to set as supported but it is not supported on FW4.16

Additional check added for SFP X722 to not enable adminq operation.
