David Teigland 760cebf47d reporting: should not fail with foreign option if lvm1 pvs exist
When lvm1 PVs are visible, and lvmetad is used, and the foreign
option was included in the reporting command, the reporting
command would fail after the 'pvscan all devs' function saw
the lvm1 PVs.  There is no reason the command should fail
because of the lvm1 PVs; they should just be ignored.
