kernel:

* Fix a bug where devices weren't cleaned up on close(): CAM_REQ_CMP != 0

user:
* Increase timeout in usermode to CAM_TIME_INFINITY.  The initiator is in
  charge of timeouts and the value was in ms, not seconds.
* Bring two debugging printfs under the debug flag
* Clean up man page to show increased testing on isp(4)
