So add a couple macros for this just like we have for csum values in btrfs_inode.h (CSUM_FMT and CSUM_FMT_VALUE). This also ensures that we consistently print a key in the same format, always as "(%llu %llu %llu)", which is the most common format we use, but we have a few variations such as "[%llu %llu %llu]" for no good reason. This patch introduces the macros while the next one makes use of it. This is to ease backports of future patches, since then we can backport this patch which is simple and short and then backport those future patches, as the next patch in the series that makes use of these new macros is quite large and may have some dependencies.
