usb: gadget: fix check in sync read from ep in gadgetfs
When reading synchronously from a non-zero endpoint, gadgetfs will
return -EFAULT even if the read succeeds, due to a bad check of the
copy_to_iter() return value.
This fix compares the return value of copy_to_iter to the amount of
bytes that was passed, and only fails if they are not the same.
