reftable/stack: fix zero-sized allocation when there are no readers
Similar as the preceding commit, we may try to do a zero-sized
allocation when reloading a reftable stack that ain't got any tables.
It is implementation-defined whether malloc(3p) returns a NULL pointer
in that case or a zero-sized object. In case it does return a NULL
pointer though it causes us to think we have run into an out-of-memory
situation, and thus we return an error.
Fix this by only allocating arrays when they have at least one entry.
