'clockid' only can be ALARM_REALTIME and ALARM_BOOTTIME. It's impossible
to return -1 and callers never check the value of -1.
Only alarm_clock_get_timespec(), alarm_clock_get_ktime(),
alarm_timer_create() and alarm_timer_nsleep() call clock2alarm(). These
callers using clockid_to_kclock() to get 'struct k_clock', this ensures
clock2alarm() never returns -1.
