Subject: [PATCH 5/8] don't print message if request_resource() failed

If register_memory_resource() fails, the caller(add_memory()) will
return -EEXIST, and add_memory() returns -EEXIST only when
register_memory_resource() fails. The function acpi_memory_enable_device()
doesn't treat such erro as a fetal error, and don't want this message.
The function that calls add_memory() has printed message if add_memory()
failed, so don't print message in register_memory_resource().
