btrfs: rename struct btrfs_io_bio to btrfs_bio
Previously we had "struct btrfs_bio", which records IO context for mirrored IO and RAID56, and "strcut btrfs_io_bio", which records extra btrfs specific info for logical bytenr bio. With "btrfs_bio" renamed to "btrfs_io_context", we are safe to rename "btrfs_io_bio" to "btrfs_bio" which is a more suitable name now. The struct btrfs_bio changes meaning by this commit. There was a suggested name like btrfs_logical_bio but it's a bit long and we'd prefer to use a shorter name. This could be a concern for backports to older kernels where the different meaning could possibly cause confusion or bugs. Comparing the new and old structures, there's no overlap among the struct members so a build would break in case of incorrect backport. We haven't had many backports to bio code anyway so this is more of a theoretical cause of bugs and a matter of precaution but we'll need to keep the semantic change in mind.
