cpuidle: governors: teo: Avoid selecting states with zero-size bins

Browse source

If the last two enabled idle states have the same target residency which
is at least equal to TICK_NSEC, teo may select the next-to-last one even
though the size of that state's bin is 0, which is confusing.

Prevent that from happening by adding a target residency check to the
relevant code path.
