Liang Chen aaf153aece page_pool: halve BIAS_MAX for multiple user references of a fragment ...

Up to now, we were only subtracting from the number of used page fragments
to figure out when a page could be freed or recycled. A following patch
introduces support for multiple users referencing the same fragment. So
reduce the initial page fragments value to half to avoid overflowing.
