Clean up and export cancel_dirty_page() to modules

Make cancel_dirty_page() act more like all the other dirty and writeback
accounting functions: test for "mapping" being NULL, and do the
NR_FILE_DIRY accounting purely based on mapping_cap_account_dirty()).

Also, add it to the exports, so that modular filesystems can use it.
