acpi/ghes: Use error_fatal in acpi_ghes_memory_errors()

Use error_fatal in acpi_ghes_memory_errors() so that the caller needn't
explicitly call exit(). The return value of acpi_ghes_memory_errors()
and ghes_record_cper_errors() is changed to 'bool' indicating an error
has been raised, to be compatible with what's documented in error.h.
