[PATCH 5.16 0456/1017] mt76: mt7921: do not always disable fw runtime-pm

[Greg Kroah-Hartman]

From: Lorenzo Bianconi <lorenzo@xxxxxxxxxx>

[ 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.
