Log:
Put a bit of hysteresis into both BUSY SCSI status returns
and CAM_RESRC_UNAVAIL returns. Delay a tunable amount for
either between retries.
This came up because the MPT IOC was returning "IOC out of
resources" for some user and this caused a CAM_RESRC_UNAVAIL
return. Putting a bit of delay between retries helped them
out.
There was some discussion that an async event should be used
to clear CAM_RESRC_UNAVAIL. That's probably a better notion
eventually.
