[PATCH 10/12] imx-usb-loader: simplify read_memory()

[Sascha Hauer <s.hauer@pengutronix.de>]

In read_memory() we transfer at maximum 64 bytes, so the returned number
of actually sent bytes will never be greater than 64 and we can drop the
corresponding checks. Then it is checked if there are really 64 bytes
transferred. We don't do this elsewhere, so drop it here as well.
