zebra: drop NEWLINK event handling in the main thread

NEWLINK is only registered by the dplane thread, the main thread
doesn't care about it. So remove the real process of `netlink_link_change()`
for NEWLINK event in main thread.

And move NEWLINK/DELLINK event to the block where the dplane messages
are kept together.
