[PATCH 4/7] governors/haltpoll: Drop kvm_para_available() check

[Mihai Carabas]

From: Joao Martins <joao.m.martins@xxxxxxxxxx>

This is duplicated already in the haltpoll idle driver,
and there's no need to re-check KVM guest availability in
the governor.

Either guests uses the module which explicitly selects this
governor, and given that it has the lowest rating of all governors
(menu=20,teo=19,ladder=10/25,haltpoll=9) means that unless it's
the only one compiled in, it won't be selected.

Dropping such check also allows to test haltpoll in baremetal.
