Optimize callout_process() to use less variables and less conditions to
implement the same logic.  Now it fits better into CPU registers, and
according to PMC significntly reduces number of resource stalls, reducing
consumed by it CPU time during usleep(1) benchmark by 30%.

Remove callout_new_inserted variable and call cpu_new_callout() function
directly.  Since most architectures are using it and there is #define to
identify others, there is no point to keep this extra indirection.
