Alexander Barkov c69fb1a627 MDEV-35864 UBSAN: "applying zero offset to null pointer" when using a Field_set with empty values ...

The val_buffer variable can come to Field_set::val_str()
with the Ptr member equal to nullptr. This caused UBSAN errors
"applying zero offset to null pointer" in my_strnncollsp_simple()
and other strnncollsp() virtual implementations. Fixing the code to
make sure its Ptr is not equal to nullptr.
