[PATCH] net/ice: fix missing return on unsupported range in FDIR

[sandeep.penigalapati at intel.com]

From: Sandeep Penigalapati <sandeep.penigalapati at intel.com>

In ice_fdir_parse_pattern(), a flow item that specifies a 'last'
member (a range) is only allowed for IPV4 and IPV6_FRAG_EXT item
types.  For other item types the code set an rte_flow error but did
not return, so parsing continued from an inconsistent state.

Add the missing return so an unsupported range aborts parsing.

Fixes: b7e8781de768 ("net/ice: support flow director for IP fragment packet")
