drivers/video/aty/radeon_base.c: notify user if sysfs_create_bin_file() failed

Browse source 
Current kernel builds warn about:
drivers/video/aty/radeon_base.c: In function 'radeonfb_pci_register':
drivers/video/aty/radeon_base.c:2334: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result
drivers/video/aty/radeon_base.c:2336: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result

Do minimal checking of these functions and issue a warning if either
fails.  They don't seem to be critical..
