[PATCH RFC v2 02/24] scsi: allocate separate queue for reserved commands

It might even get worse, as during device setup things like
'slave_alloc' etc is getting called, which has a fair chance of getting
confused for non-existing devices.
Cf qla2xxx:qla2xx_slave_alloc() is calling starget_to_rport(), which
will get us a nice oops when accessing a target which is _not_ the child
of a fc remote port.
And this is why I'm not utterly keen on this approach; auditing all
these callbacks is _not_ fun.
Cheers,
Hannes
