apply multipath_component_detection=0 to duplicate PV handlinglvm2-2.03.14-6.el8rhel-8.7.0
multipath_component_detection=0 has always applied to the filter-based
component detection. Also apply this setting to the duplicate-PV
handling which also eliminates multipath components (based on duplicate
PVs having the same wwid.)
