x86: PM: Make APM idle driver initialize polling state
commit f859422075165e32c00c8d75d63f300015cc07ae upstream.
Update the APM driver overlooked by commit 1b39e3f813b4 (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: 1b39e3f813b4 (cpuidle: Make drivers initialize polling state)
