[PATCH 3/4 v2] btrfs-progs: mkfs: refactor create_data_reloc_tree

[Yingyi Luo <yingyil@google.com>]

From: yingyil <yingyil@google.com>

Add an objectid parameter to make the function a general one for
inserting root items and rename it to create_tree. The change cascades
down to the callchain.

v2: utilize create_tree() function for creating a subvolume, instead of
create_subvol() in convert/main.c.
