If we're waiting for tens or hundreds of milliseconds we will just go to
sleep instead of spinning.

'schluffen()' essentially duplicates the functionality of the standard
Linux 'interruptible_sleep_on()' function.
There may still be some race conditions that can be closed here, but
most of the command queue processing is sloted for conversion to
something more like in the single span driver in order to reduce the
time in interrupt context spent scanning for commands to the modules.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
