Ben Dooks d585dfe840 S3C2410: add error print if we cannot add attribute
Fix the following warning by checking the result of device_create_file and
printing an error but not removing the device (loss of debug registers is
not fatal).

drivers/video/s3c2410fb.c:905: warning: ignoring return value of 'device_create_file', declared with attribute warn_unused_result
