Remove an unnecessary call to pmap_remove_all() and the associated "XXX" comments from vnode_pager_setsize().  This call was introduced in revision 1.140 to address a problem that no longer exists. Specifically, pmap_zero_page_area() has replaced a (possibly) problematic implementation of page zeroing that was based on vm_pager_map(), bzero(), and vm_pager_unmap().
