octeontx2-af: fix detection of IP layer

Browse Source 
[ Upstream commit 404dc0fd6fb0bb942b18008c6f8c0320b80aca20 ]

Checksum and length checks are not enabled for IPv4 header with
options and IPv6 with extension headers.
To fix this a change in enum npc_kpu_lc_ltype is required which will
allow adjustment of LTYPE_MASK to detect all types of IP headers.
