mm: declare some external symbols
Declare 'bdi_pending_list' and 'tag_pages_for_writeback()' to remove
following sparse warnings:
mm/backing-dev.c:46:1: warning: symbol 'bdi_pending_list' was not declared. Should it be static?
mm/page-writeback.c:825:6: warning: symbol 'tag_pages_for_writeback' was not declared. Should it be static?
