Subject: [PATCH] net/i40e: fix FDIR input set conflict

[ upstream commit fade5c874397f24770b2464903ddc2c423a034b6 ]

The first FDIR rule for some PCTYPE will configure input set and
create flow, the following flows must use the same input set,
otherwise it will cause input set conflict and fail to create flow.
If it creates the first rule after flow flush, input set should be
re-configured.

Fixes: 42044b69c67d ("net/i40e: support input set selection for FDIR")
