Fix vgsplit locking and remove unneeded error messages when split into new VG.

When vg_lock_and_read() calls were added, they were done so incorrectly for
the destination VG (vg_to).  This resulted in the VG lock not obtained when
a new VG was the destination (vg_lock_and_read() would fail in the vg_read()
clause, which would then release the lock before returning NULL), and could
result in corrupted destination VG.

The fix was to put back the original lock_vol() and vg_read() calls for 'vg_to'.
The failure of vg_read() indicates "vg does not exist", and we key off that
to determine whether we are dealing with a new or existing VG as the
destination.
