[arbel] Improve debugging output and facilities 

Improve the utility of debugging messages by including the relevant
port number, queue number (QPN, CQN, EQN), work queue entry (WQE)
number, and physical addresses wherever applicable.

Add arbel_dump_cqctx() for dumping a completion queue context and
arbel_dump_qpctx() for dumping a queue pair context.
