x86/resctrl: Check all domains are offline in resctrl_exit()
resctrl_exit() removes things like the resctrl mount point directory
and unregisters the filesystem prior to freeing data structures that
were allocated during resctrl_init().
This assumes that there are no online domains when resctrl_exit() is
called. If any domain were online, the limbo or overflow handler could
be scheduled to run.
Add a check for any online control or monitor domains, and document that
the architecture code is required to offline all monitor and control
domains before calling resctrl_exit().
