format1: Fix snapshot reload in lv_remove.

Browse Source 
The special suspend/resume code in lv_remove for LVM1 snapshots was interpsersed
with a vg_commit call. However, while with LVM1 metadata, vg_commit is
technically a no-op, the activation code relied on the ondisk and incore
metadata being the same, since on LVM1, a "commit" happens in vg_write
already. Since the "ondisk" metadata was previously not available with format1
(and incore was silently used instead, via lvmcache), the problem was masked.
