PAGE_CLEAR_DIRTY and PAGE_SET_WRITEBACK are two macros used in
__process_pages_contig(), to inform the function to clear page dirty and
then set page writeback.

However page write back and dirty are two conflict status (at least for
sector size == PAGE_SIZE case), this means those two macros are always
called together.

This means we can merge PAGE_CLEAR_DIRTY and PAGE_SET_WRITEBACK, into
one macro, PAGE_START_WRITEBACK.
