Input: sur40 - fix an error code in sur40_probe() 

[ Upstream commit b0b7d2815839024e5181bd2572f5d8d4f65363b3 ]

If v4l2_ctrl_handler_setup() fails then probe() should return an error
code instead of returning success.

Fixes: cee1e3e2ef ("media: add video control handlers using V4L2 control framework")
