[PATCH librdmacm] rsocket: Segmentation fault fix in case of multiple connections

[Ilya Nelkenbaum]

From: Ilya Nelkenbaum <ilyan-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

In case of more than 16 rsocket connections
are established, "svc->rss" buffer is reallocated
with more memory. Index 0 is reserved for the service's
communication socket, and this is not taken in count
when data is copied from old buffer location to
new one.
