Add a check for the sysfs_create_bin_file() return value.
In case of error the framebuffer creation is not aborted, but a warning message is generated instead.

The aim of this patch is to remove the following warning messages:
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
The patch was already acknowledged by Benjamin Herrenschmidt, but I realised that I did not cc the LKML (sorry for that).
