net/i40e: fix ethertype filter on X722

The GL_SWR_PRI_JOIN_MAP registers are effective on filters, changing
the register's default value will fail the ethertype filter.

The GL_SWR_PRI_JOIN_MAP values are different for each NIC, and current
X722 register values are wrong.

Fix X722 ethertype filter by setting registers to X722 default NVM
values.
