V4L/DVB (5900): usbvision: fix bugs [sg]_register functions
s_register was assigning the return code to (unsigned)reg->val, rather than
errCode, which it what it would return. Except reg->val can't be < 0, so it
would never actually return an error.
g_register never actually put the value it read into reg->val.
