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.
