dm snapshot: require non zero chunk size by end of ctr
commit 3f2412dc85260e5aae7ebb03bf50d5b1407e3083 upstream.
If we are creating snapshot with memory-stored exception store, fail if
the user didn't specify chunk size. Zero chunk size would probably crash
a lot of places in the rest of snapshot code.
