Switch out fixes for CPUs.

src/cpu/o3/cpu.cc:
    Fix up keeping proper state when switched out and drained.
src/cpu/simple/timing.cc:
src/cpu/simple/timing.hh:
    Keep track of the event we use to schedule fetch initially and upon resume.  We may have to cancel the event if the CPU is switched out.
