dmaengine: avoid non-constant format string

Using an arbitrary string as a printf-style format can be a security
problem if that string contains % characters, as the optionalal
-Wformat-security flag points out:

drivers/dma/dmaengine.c: In function '__dma_async_device_channel_register':
drivers/dma/dmaengine.c:1073:17: error: format not a string literal and no format arguments [-Werror=format-security]
 1073 |                 dev_set_name(&chan->dev->device, name);
      |                 ^~~~~~~~~~~~

Change this newly added instance to use "%s" as the format instead to
pass the actual name.
