net/i40e: fix pctype configuration for X722

[ upstream commit b95179d ]

To make X722's PCTYPE is compatible with X710, the PCTYPE in the
FD programming descriptor is translated into different types by using
GLQF_FD_PCTYPE table. But the types of 'UNICAST_IPV4_UDP'
and 'MULTICAST_IPV4_UDP' are only supported for X722, so that
the corresponding registers can not be configured after translation.

This patch removes the transition before the FD filter is programmed.
