ALSA: hda - Fix return value of snd_hda_check_power_state()
The refactoring by commit 9040d102 introduced the new function
snd_hda_check_power_state(). This function is supposed to return true
if the state already reached to the target state, but it actually
returns false for that. An utterly stupid typo while copy & paste.
Fortunately this didn't influence on much behavior because powering up
AFG usually powers up the child widgets, too. But the finer power
control must have been broken by this bug.
