[dpdk-dev] [PATCH] node: fix arm64 build issue for older gcc

[Nithin Dabilpuram]

Older GCC(~4) complains about uninitialized 'dip'
var though all the lanes of the vec register are set.
Hence this patch explicitly initializes vec register
to fix the issue.

Fixes: 16df6a2c6671 ("node: add IPv4 lookup for arm64")
