There is no point in calling dma_supported() before calling
dma_set_coherent_mask(). This function already calls dma_supported() and
returns an error (-EIO) if it fails.
So remove the superfluous dma_supported() call.
While at it, fix the name of the function reported in a dev_err().

I guess that the whole while loop could be removed, but I don't remind the
thread with the corresponding explanation, so leave it as-is :(
