dm: core: Fix Handling of global_data moving in SPL

commit 2f11cd9121658 ("dm: core: Handle global_data moving in SPL")
handles relocation of GD in SPL if spl_init() is called before
board_init_r(). So, uclass_root.next need not be initialized always
and accessing uclass_root.next->prev gives an abort. Update the
uclass_root only if it is available.
