media: usb: siano: Fix false-positive "uninitialized variable" warning

commit 45457c01171fd1488a7000d1751c06ed8560ee38 upstream.

GCC complains about an apparently uninitialized variable recently
added to smsusb_init_device().  It's a false positive, but to silence
the warning this patch adds a trivial initialization.
