Give some indication of the CCB that's in flight when we panic.

Print the pointer to ccb so we can find it (for what good it does)
as well as the type of operation in flight when the cam_path has
been freed out from under us. This helps both core analysis as well
as automated systems that collect panic strings but little else.
