MDEV-4252 geometry query crashes server.
The bug was found by Alyssa Milburn.
If the number of points of a geometry feature read from
binary representation is greater than 0x10000000, then
the (uint32) (num_points * 16) will cut the higher byte,
which leads to various errors.
Fixed by additional check if (num_points > max_n_points).
