net/ice: fix FDIR flow type for IPv4 fragment

When creating FDIR rule and parsing the pattern, if IPv4 fragment type is
detected, the flow type is not changed to ICE_FLTR_PTYPE_FRAG_IPV4 from
ICE_FLTR_PTYPE_NONF_IPV4_OTHER. It will cause profile confilict with
other FDIR rules for IPv4 other type.
