net/i40e: add packet type translation for X722

To make the PCTYPE in x722 compatible with original PCTYPE in
flow director (FD) filters, the PCTYPE in the FD programming
descriptor needs to be translated into a different PCTYPE using
GLQF_FD_PCTYPE table.
Translation needs to be done before the FD filter is programmed.
