cpu,o3: Fixed checkpointing bug occuring in the o3 CPU

Checkpointing a system with out-of-order CPUs might get stuck if
one of the CPUs has been put to sleep. The quiesce instruction
cannot get drained hence checkpointing never finishes.

This commit resolves that by activating all suspended thread
contexts when draining the system.
