[libcamera-devel] [PATCH 2/6] libcamera: v4l2_videodevice: Fix ordering of debug statement

The "Opened device" statement occurs before the buffertype_ is set.

This causes all devices to report that they are [out] devices at open()
regardless of their type.

As the message operates in the past-tense, move the statement to the end
of the function when all work has been completed.

Fixes: 04d5be7f76fe ("libcamera: v4l2_device: Inherit from Loggable to
                      print device node name")
