Simon Glass 8d7ff12e63 acpi: Allow creating the GNVS to fail
In some cases an internal error may prevent this from working. Update the
function return value and report the error. At present the API for writing
tables does not easily support reporting errors, but once it is fully
updated to use a context pointer, this will be easier.
