Bug#11908153: CRASH AND/OR VALGRIND ERRORS IN FIELD_BLOB::GET_KEY_IMAGE
Field_geom::reset() failed to reset its base Field_blob.
The range optimizer used the un-initilized field during optimization and execution.
mysql-test/r/gis.result:
New test case.
mysql-test/t/gis.test:
New test case.
sql/field.h:
Field_geom::reset() must call Field_blob::reset(), even if the field is not nullable.
