USB: Avoid NULL pointer deref in usb_hcd_alloc_bandwidth. usb_ifnum_to_if() can return NULL if the USB device does not have a configuration installed (usb_device->actconfig == NULL), or if we can't find the interface number in the installed configuration. Return an error instead of crashing. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
