[PATCH] drm/amdgpu: Print once if RAS unsupported

[Luben Tuikov]

MESA polls for errors every 2-3 seconds. Printing with dev_info() causes
the dmesg log to fill up with the same message, e.g,

[18028.206676] amdgpu 0000:0b:00.0: amdgpu: df doesn't config ras function.

Make it dev_info_once(), as it isn't something correctible during boot, so
printing just once is sufficient. Also sanitize the message.
