metadata: Nuke the exported "pv_read" function.

The toollib code for processing PVs given on commandline tried to be smart and
use pv_read, avoiding real metadata scanning. The premise of the optimisation
was that if there is an active MDA on the PV, it can be reliably used to
establish VG membership. This assumption is however wrong, since it's entirely
possible that this particular MDA is simply out of date, and the PV is not
actually in any VG. While this is a subtle and rare bug, it's still a bug. One
way to trigger it would be to hotplug an old disk which at some point was a PV
in an existing VG, having a seemingly valid MDA but with an old sequence
number. All commands that use normal scanning realize that this PV does not
belong into the VG anymore, but anything based on pv_read alone will believe it
does.
