Martin Hansson e33e01e516 Bug#44684: valgrind reports invalid reads in ...

Item_func_spatial_collection::val_str
        
When the concatenation function for geometry data collections
reads the binary data it was not rigorous in checking that there
is data available, leading to invalid reads and crashes.
Fixed by making checking stricter.
