[PATCH-for-5.0 09/12] hw/mips/mips_malta: Add missing error-propagation code

[Philippe Mathieu-Daudé]

Running the coccinelle script produced:

  $ spatch \
    --macro-file scripts/cocci-macro-file.h --include-headers \
    --sp-file scripts/coccinelle/object_property_missing_error_propagate.cocci \
    --keep-comments --smpl-spacing --dir hw

  [[manual check required: error_propagate() might be missing in 
object_property_set_int() hw/mips/mips_malta.c:1193:4]]
  [[manual check required: error_propagate() might be missing in 
object_property_set_str() hw/mips/mips_malta.c:1192:4]]

Add the missing error_propagate() after manual review by adding
a Error* parameter to create_cps().
