[dpdk-dev] [v2] net/i40e: fix SFP X722 not work with FW4.16

[Xiao Zhang]

FW4.16 of SFP X722 does not support setting TPID by set_switch_config
adminq operation, for firmware version less than 4.16 TPID is set by
register instead. For device SFP X722, disable adminq flag to follow
the same path with old firmware version to make it work.

v2
Unset adminq flag instead of only checking device id when set TPID.
v1
Check device id when setting TPID, use adminq if not SFP X722, else
use register.
