[PATCH v2 03/17] migration/multifd: Zero p->flags before starting filling a packet

[Maciej S. Szmigiero]

From: "Maciej S. Szmigiero" <maciej.szmigi...@oracle.com>

This way there aren't stale flags there.

p->flags can't contain SYNC to be sent at the next RAM packet since syncs
are now handled separately in multifd_send_thread.
