[PATCH 2/3] mm/page-writeback.c: Fix comment of wb_domain_writeout_add()

[Tang Yizhou]

From: Tang Yizhou <yizhou.tang@xxxxxxxxxx>

__bdi_writeout_inc() has undergone multiple renamings, but the comment
within the function body have not been updated accordingly. Update it
to reflect the latest wb_domain_writeout_add().
