[PATCH v2 23/23] examples/l3fwd-power: resolve shadow variable warnings

[Stephen Hemminger]

Rename function parameters to avoid shadowing the file-scope
static arrays ipv4_l3fwd_lookup_struct and ipv6_l3fwd_lookup_struct.
The new parameter names ipv4_lookup_struct and ipv6_lookup_struct
match the member names used in struct lcore_conf.

Fixes warnings with -Wshadow for get_ipv4_dst_port (both exact-match
and LPM variants) and get_ipv6_dst_port.
