f2fs crypto: add filename encryption for roll-forward recovery
This patch adds a bit flag to indicate whether or not i_name in the inode
is encrypted.
If this name is encrypted, we can't do recover_dentry during roll-forward.
So, f2fs_sync_file() needs to do checkpoint, if this will be needed in future.
