lvol: introduce lvs_alloc()

Browse Source 
There are multiple locations where a struct lvol_store is allocated.
This invites inconsistency in initialization, which will become more of
a problem as esnap clones have additional initialization.

Now all struct lvol_store allocations should be done with lvs_alloc().
