Fix fastboot flash bug.

If the downloading file size is equal to the partition size, "fastboot flash" can't work, at least in sunxi platform, because used an uninitalized point: ep->desc.

This patch also fixed 'data abort' bug in am335x platform.

Reproduce: fastboot flash loader1 spl/sunxi-spl.bin.
