usb: check device is not NULL before calling usb_ep_get()
In musb_packet(), the call to usb_find_device() can return NULL
if it doesn't find a device matching 'addr' so explicitly check
the return value before passing it to usb_ep_get(). This then
allows the subsequent calculation of 'id' to be streamlined.
