net/i40e: fix X722 performance

Lack of GL_SWR_PM_UP_THR value for mac type 4x10G X722 caused it can't
reach line rate in one queue one core forwarding case. It's about 1%
performance drop.  This patch adds value as:

 Device-ID  Value        Comments
 0x37D0    0x03030303   4x10G FPK

This value is hardware specific.
