regulator: Fixes for v6.2

Two core fixes here, one for a long standing race which some Qualcomm
 systems have started triggering with their UFS driver and another fixing
 a problem with supply lookup introduced by the fixes for devm related
 use after free issues that were introduced in this merge window.
