Log Message:
In Idle(), only switch to the idle PCB if we're not already running
on it, and make sure to deactivate the old process's address space,
as this will not otherwise be done by cpu_switch() later once we're
on the idle PCB.

Also, update some comments related to when s0 (i.e. the old process)
is NULL in the context switching code.
