The prepare_lock_switch() function has an unused parameter, and also the
function name was not descriptive. To improve readability and remove
the extra parameter, do the following changes:
* Move prepare_lock_switch() from kernel/sched/sched.h to
kernel/sched/core.c, rename it to prepare_task(), and remove the
unused parameter.
* Split the smp_store_release() out from finish_lock_switch() to a
function named finish_task.
* Comments ajdustments.
