gfs2: Convert to new freezing mechanism
We update gfs2_page_mkwrite() to use new freeze protection and the transaction code to use freeze protection while the transaction is running. That is needed to stop iput() of unlinked file from modifying the filesystem. The rest is handled by the generic code.
