cmd_spi: remove broken signed casting for display
Since we're working with unsigned data, you can't apply a signed pointer cast and then attempt to print the result. Otherwise you get wrong output when the sign bit is set like "0xFF" incorrectly extended to "0xFFFFFFFF". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
