Fix uninitialized stack local, VPP-581
Sporadically messes up the client message allocation ring, by setting c->message_bounce[msg_id] non-zero. A day-1 bug, made blatantly obvious by the python API language binding for no particular reason. Change-Id: I11084dd884622e7b44bdabb922466c4d07138235 Signed-off-by: Dave Barach <dave@barachs.net>
