[ Upstream commit b44eeb8cbdf2b88f2844f11e4f263b0abed5b5b0 ]
After commit 'd430dffbe9dd ("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.
