Please do not reserve a slot for device commands in MCQ mode but instead
queue device management commands on the device management command queue
in MCQ mode. Please also add WARN_ON_ONCE() statements in the code that
uses hba->reserved_slot to make sure that that variable is not used in
MCQ mode.
Thanks,
Bart.
