pktcdvd: consolidate DPRINTK and VPRINTK macros
Use the more common pkt_dbg(level, fmt, ...) form. These messages are emitted at KERN_NOTICE. Always emit function name with pkt_dbg(2, ...) uses and remove the sometimes abbreviated embedded function name. This form always verifies the format and arguments.
