Currently on-disk structure is able to keep only 16bit project quota id, so disallow 32bit ones. This fixes a problem where part of kernel structures holding project quota id uses 32bit variable while part (on-disk) uses 16bit variable which causes project quota member files to be inaccessible for some operations (like mv/rm).
