net/ice/base: make FDID available for flex descriptor

The FDID (flow director filter ID) was not inserted into Flex Descriptor
writebacks. The data for FDID is always 0xffffffff when FDID-priority is
0 in the flow director programming descriptor.

This patch changes the FDID-priority to 1 so the FDID is available for
the Flex Descriptor. With this patch the FDID is placed into the Flex
Descriptor.
