linux-user: Reset copied CPUs in cpu_copy() always

When a new thread gets created, we need to reset non arch specific state to
get the new CPU into clean state.

However this reset should happen before the arch specific CPU contents get
copied over. Otherwise we end up having clean reset state in our newly created
thread.
