msm: kgsl: Fix race condition while making page as dirty
set_page_dirty() is racy if the caller has no
reference against page->mapping->host, and if
the page is unlocked. This is because another
CPU could truncate the page off the mapping and
then free the mapping.
Use set_page_dirty_lock() to avoid this race condition.
