kernel: timeout: avoid identifier collisions

MISRA-C Rule 5.3 states that identifiers in inner scope should
not hide identifiers in outer scope.

In the function z_set_timeout_expiry(), the parameter "idle"
and an inner variable "next" collide with function named idle()
and next(). So rename those variables.
