media: i2c/tw9906: Fix potential memory leak in tw9906_probe()
[ Upstream commit cad237b6c875fbee5d353a2b289e98d240d17ec8 ]
In one of the error paths in tw9906_probe(), the memory allocated in
v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that
by calling v4l2_ctrl_handler_free() on the handler in that error path.
