Similar to the cpu_rev_var and cpu_ger_rev_var functions, inline the call_reset_handler handler. This way we skip the costly branch at no extra cost as this is the only place where this is called. While we're at it, drop the options for CPU_NO_RESET_FUNC. The only cpus that need that are virtual cpus which can spare the tiny bit of performance lost. The rest are real cores which can save on the check for zero. Now is a good time to put the assert for a missing cpu in the get_cpu_ops_ptr function so that it's a bit better encapsulated.
