Daniel Black 96045fb53a MDEV-37052: JSON_TABLE stack overflow handling errors ...

The recursive nature of add_table_function_dependencies
resolution meant that the detection of a stack overrun
would continue to recursively call itself.
Its quite possible that a user SQL could get multiple
ER_STACK_OVERRUN_NEED_MORE errors.

Additionaly the results of the stack overrrun check
result was incorrectly assigned to a table_map result.

Its only because of the "if error" check after
add_table_function_dependencies is called, that would
detected the stack overrun error, prevented a
potential corruped tablemap is from being processed.

Corrected add_table_function_dependencies to stop and
return on the detection of a stack overrun error.

The add_extra_deps call also was true on a stack overrun.
