vgchange autoactivation: lock vg early to avoid second label scan

Copy another optimization from pvscan -aay to vgchange -aay.
When using the optimized label scan for only one VG, acquire the
VG lock prior to the scan.  This allows vg_read to then skip the
repeated label scan that normally happens after locking the vg.
