libcamera: v4l2_device: List controls when setting file descriptor
The base V4L2Device class is bound to a video device node by either
open(), which opens the device node and creates a new file descriptor,
or setFd(), which takes an already open file descriptor. The former
populates the V4L2Device instance controls, while the latter doesn't.
This prevents using controls on V4L2 M2M devices. Fix it by populating
controls in setFd(), which is called by open().
