cpus-common: remove redundant call to exclusive_idle()
No need to call exclusive_idle() from cpu_exec_end since it is done immediately afterwards in cpu_exec_start. Any exclusive section could run as soon as cpu_exec_end leaves, because cpu->running is false and the mutex is not taken, so the call does not add any protection either.
