uwb: init beacon cache entry before registering uwb device

commit 675f0ab2fe5a0f7325208e60b617a5f32b86d72c upstream.

Make sure the uwb_dev->bce entry is set before calling uwb_dev_add in
uwbd_dev_onair so that usermode will only see the device after it is
properly initialized.  This fixes a kernel panic that can occur if
usermode tries to access the IEs sysfs attribute of a UWB device before
the driver has had a chance to set the beacon cache entry.
