btrfs: Convert to new freezing mechanism
We convert btrfs_file_aio_write() to use new freeze check. We also add proper freeze protection to btrfs_page_mkwrite(). We also add freeze protection to the transaction mechanism to avoid starting transactions on frozen filesystem. At minimum this is necessary to stop iput() of unlinked file to change frozen filesystem during truncation. Checks in cleaner_kthread() and transaction_kthread() can be safely removed since btrfs_freeze() will lock the mutexes and thus block the threads (and they shouldn't have anything to do anyway).
