Subject: [PATCH] apply multipath_component_detection=0 to duplicate PV
handling
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.)
