hw/acpi/erst: Do not ignore Error* in realize handler
erst_realizefn() passes @errp to functions without checking for failure. If it runs into another failure, it trips error_setv()'s assertion. Use the ERRP_GUARD() macro and check *errp, as suggested in commit ae7c80a7bd ("error: New macro ERRP_GUARD()").
