[PATCH v2] btrfs-progs: delete unused is_vol_small() and BTRFS_MKFS_SMALL_VOLUME_SIZE

[Anand Jain]

Since commit c11e36a29e84 (Btrfs-progs: Do not force mixed block group
creation unless '-M' option is specified) we don't have automatic
mixed mode, and the function is_vol_small() and
the define BTRFS_MKFS_SMALL_VOLUME_SIZE become obsolete, so clean it up.
