RE: [PATCH 09/23] verbs: Fix incorrect type of len

gcc remarks:

../librdmacm/examples/udpong.c:301:11: warning: comparison of unsigned
expression < 0 is always false [-Wtype-limits]
   if (len < 0)

len is set by:
		len = svr_recv(&msg, sizeof msg, &addr, &addrlen);

And svr_recv returns:

static ssize_t svr_recv(struct message *msg, size_t size,

So clearly len is the wrong type, and the error test does
not work.
