[PATCH] drivers: musb_gadget: Save endpoint desc to usb_ep->desc
From: qianfan Zhao qianfanguijin@163.com
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.
Reproduce: fastboot flash loader1 spl/sunxi-spl.bin.

This also needs to be set to NULL in disabled.
