Oleksandr Byelkin 0d35fe6e57 MDEV-35326: Memory Leak in init_io_cache_ext upon SHUTDOWN ...

The problems were that:
1) resources was freed "asimetric" normal execution in send_eof,
 in case of error in destructor.
2) destructor was not called in case of SP for result objects.
(so if the last SP execution ended with error resorces was not
freeded on reinit before execution (cleanup() called before next
execution) and destructor also was not called due to lack of
delete call for the object)

Result cleanup() renamed to reset_for_next_ps_execution() to better
reflect function().

All result method revised and freeing resources made "symetric".

Destructor of result object called for SP.

Added skipped invalidation in case of error in insert.

Removed misleading naming of reset(thd) (could be mixed with
with reset()).
