usb: dwc3: trace: don't save pointers
There was another instance where we were holding pointers which could be long gone. Fix that by caching only values pointed to by such pointer. Because no crash has been observed, this patch will be sent on v3.19 merge window, instead of -rc. Signed-off-by: Felipe Balbi <balbi@ti.com>
