b=21406 fix deadlock between kjournald2 and ost_io thread

i=adilger
i=girish

Calling clear_page_dirty_for_io() is no longer needed since
we are granted that no dirty pages can be left in the page
cache by partial truncate. The problem is that
clear_page_dirty_for_io() can temporarilly mark the page
as dirty in the radix tree, which can cause deadlock
between jbd commit and bulk write handling.
