[PATCH] examples/l2fwd-event: fix memset of port statistics array

[Dragos Tarcatu]

port_stats is declared as struct l2fwd_port_statistics[RTE_MAX_ETHPORTS],
but the memset passed sizeof(struct l2fwd_port_statistics) -- the size
of a single element -- leaving ports 1 through RTE_MAX_ETHPORTS-1 with
uninitialized stats. Use sizeof(rsrc->port_stats) to clear the whole
array regardless of RTE_MAX_ETHPORTS.

Surfaced as a -Wmemset-elt-size warning when building with
-Dmax_ethports=64 -Dexamples=all.

Fixes: 4ff457986f76 ("examples/l2fwd-event: add default poll mode routines")
