usb: renesas_usbhs: Use struct assignment instead of memcpy()
To avoid the error-proneness of calls to sizeof() in the memcpy,
this patch uses struct assignment instead of memcpy.

Reviewed-by: Simon Horman <horms+renesas@verge.net.au>---
This patch is based on Greg's linux-usb.git / usb-next branch.
Note that mod_host.c also has memcpy but we cannot use struct assignment
for it because the type of urb->setup_patcket is just "unsigned char *".
