mt76: mt7921: do not always disable fw runtime-pm

Browse source 
After commit 'd430dffbe9 ("mt76: mt7921: fix a possible race
enabling/disabling runtime-pm")', runtime-pm is always disabled in the
fw even if the user requests to enable it toggling debugfs node since
mt7921_pm_interface_iter routine will use pm->enable to configure the fw.
Fix the issue moving enable variable configuration before running
mt7921_pm_interface_iter routine.
