[PATCH-for-5.1 v3 04/24] hw/arm/aspeed_ast2600: Simplify use of Error*

[Philippe Mathieu-Daudé]

Coccinelle reported:

  $ spatch ... --timeout 60 --sp-file \
    scripts/coccinelle/simplify-init-realize-error_propagate.cocci
  HANDLING: ./hw/arm/aspeed_ast2600.c
  >>> possible moves from aspeed_soc_ast2600_init() to 
aspeed_soc_ast2600_realize() in ./hw/arm/aspeed_ast2600.c:243

While reviewing we notice we don't need two different Error*,
drop the one less used.
