Btrfs-progs: move btrfs_fsck_reinit_root to cmds-check.c

cmds-check.c contains the only caller of btrfs_fsck_reinit_root;
moving it to the caller's source file gets ctree.c a little
closer to kernelspace, although it does require exporting
add_root_to_dirty_list(), which is not done in kernelspace.
