V4L/DVB (13239): saa7146: fix memory leakage in pagetable-handling

In buffer_release() the previously allocated pagetables are not
freed,  which might result in a memory leak in certain application
use-cases, where the frame format is changed from planar format to
non-planar format. The fix explicitely frees the page tables when a
format change is done and when buffer_release() is called.
