drivers: musb_gadget: Save endpoint desc to usb_ep->desc
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.
