prism54: off by one BUG_ON() test

This code was supposed to trigger a BUG() if we truncate the output but it's off by one so it allows one character to be truncated. Really drivers shouldn't call BUG_ON() and especially for something minor like this so I've changed it to a WARN_ON().

Thanks, applied to wireless-drivers-next.git.
