[lvm-devel] [PATCH 2/4] Update vg_remove_single_* functions to use the removed_pvs list.

[Dave Wysochanski]

Now that we've split vg_remove_single into two routines, in the first routine
that only manipulates memory, we move the PVs from the vg->pvs list to the
vg->removed_pvs list.  Then later, we iterate through this list to write the
removed PVs to disk, which removes them from the volume group and places them
into the internal ORPHAN VG.
