Kieran Bingham 03fcc154eb libcamera: v4l2_device: Simplify exportBuffers()
exportBuffers() can only operate on an existing BufferPool allocation. The
pool identifies its size through its .count() method.

Passing a count in to the exportBuffers() call is redundant and can be
incorrect if the value is not the same as the BufferPool size.

Simplify the function and remove the unnecessary argument, correcting all uses
throughout the code base.

While we're here, remove the createBuffers() helper from the V4L2DeviceTest
which only served to obfuscate which pool the buffers were being allocated for.
