zebra: fix installing an evpn neighbor update

Browse Source 
Fix the function encoding evpn neighbor. The size of the buffer
for the netlink message wasn't correct and because of that we thought that
the message didn't fit entirely in the buffer and thus we were not sending
the update to the kernel.
