farsync: fix info leak in ioctl

[ Upstream commit 96b340406724d87e4621284ebac5e059d67b2194 ]

The fst_get_iface() code fails to initialize the two padding bytes of
struct sync_serial_settings after the ->loopback member. Add an explicit
memset(0) before filling the structure to avoid the info leak.
