labels: avoid label_read when getting fmt in vg_read
When vg_read() begins, it looks up the format (fmt) for
the VG name in lvmcache, telling lvmcache_fmt_from_vgname()
to reread labels on all devices in the VG.
Avoid rereading the labels on all the devices, and trust
that lvmcache has correct information. If the format of
the VG is not available, the calling code already
rescans labels and retries.
