libcamera: FrameBuffer: Add a setRequest() interface

Browse Source 
Add the ability to set the Request a buffer is associated with. This is
needed for buffers that live inside a pipeline handler and is
temporarily associated with a request as it's being processed inside the
pipeline.

While we are at it delete a stray semicolon.
