Subject: [PATCH net-next] neighbor: Initialize protocol when new pneigh_entry are created

From: David Ahern <dsahern@...il.com>

pneigh_lookup uses kmalloc versus kzalloc when new entries are allocated.
Given that the newly added protocol field needs to be initialized.

Fixes: df9b0e30d44c ("neighbor: Add protocol attribute")
