Alex Bennée 1f81ce90e3 linux-user: properly "unrealize" vCPU object ...

We shouldn't be messing around with the CPU list in linux-user save
for the very special case of do_fork(). When threads end we need to
properly follow QOM object lifetime handling and allow the eventual
cpu_common_unrealizefn to both remove the CPU and ensure any clean-up
actions are taken place, for example calling plugin exit hooks.

There is still a race condition to avoid so use the linux-user
specific clone_lock instead of the cpu_list_lock to avoid it.
