usb: gadget: r8a66597: Add missing null check on return from platform_get_resource
[ Upstream commit 9c2076090c2815fe7c49676df68dde7e60a9b9fc ]
The call to platform_get_resource can potentially return a NULL pointer
on failure, so add this check and return -EINVAL if it fails.
Fixes: c41442474a26 ("usb: gadget: R8A66597 peripheral controller support.")
