[PATCH] device-mapper snapshot: load metadata on creation

Move snapshot metadata loading to happen when the table is created instead of
when the device is resumed.  Writes to the origin device don't trigger
exceptions until each snapshot table becomes active when resume() is called on
each snapshot.

If you're using lvm2, for this patch to work properly you should update to
lvm2 version 2.02.01 or later and device-mapper version 1.02.02 or later.
