This patch just changes the functions where the device information is already available. Some cases remain where the root or fs_info is not passed to the function emitting the error. This may introduce some confusion with volumes backed by multiple devices emitting errors referring to the primary device in the set instead of the one on which the error occurred. Use btrfs_printk(fs_info, format, ...) rather than writing the device string every time, and introduce macro wrappers ala XFS for brevity. Since the function already cannot be used for continuations, print a newline as part of the btrfs_printk() message rather than at each caller.
