cpuidle: poll_state: Fix default time limit

Browse Source 
The default time is declared in units of microsecnds,
but is used as nanoseconds, resulting in significant
accounting errors for idle state 0 time when all idle
states deeper than 0 are disabled.

Under these unusual conditions, we don't really care
about the poll time limit anyhow.

Fixes: 800fb34a99 ("cpuidle: poll_state: Disregard disable idle states")
