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

Browse Source 
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.
