x86: PM: Make APM idle driver initialize polling state

Browse Source 
Update the APM driver overlooked by commit 1b39e3f813 (cpuidle: Make
drivers initialize polling state) to initialize the polling state like
the other cpuidle drivers modified by that commit to prevent cpuidle
from crashing.

Fixes: 1b39e3f813 (cpuidle: Make drivers initialize polling state)
