hpsa: use block layer tag for command allocation
Rework slave allocation:
- separate the tagging support setup from the hostdata setup
- make the hostdata setup act consistently when the lookup fails
- make the hostdata setup act consistently when the device is not added
- set up the queue depth consistently across these scenarios
- if the block layer mq support is not available, explicitly enable and
activate the SCSI layer tcq support (and do this at allocation-time so
that the tags will be available for INQUIRY commands)
Tweak slave configuration so that devices which are masked are also
not attached.
