Scott Long ff1e67ab93 Fix the mly driver! If card resources became unavailable, the driver would
correctly tell CAM to requeue the command and then freeze it's queue.  The
problem was that when resources became available again, it wouldn't tell
CAM to unfreeze it's queue, so no more commands would ever be delivered.
This is simialr to the bug that was fixed in the cciss driver last year.
This is a bug in 4-STABLE also, but is probably masked by the OS being
fast enough to drain the completion queue before it fills up.
Also add some diagnostics avaialble when compiled with MLY_DEBUG.
Thanks very much to LSI Corp for donating equipment to track this down,
and Vaidus Damosevicius for pestering me long enough to get it fixed.
