Commit Message

Fix limit check in narrow_conv_backprop().

Thanks to Sergey Kaplun.

(cherry picked from commit e45fd4cb7)

The function `narrow_conv_backprop()` does not include a limit check for
the stack pointer (`nc->sp`), even though its value may change after
several recursive calls. As a result, it leads to stack-buffer-overflow
during the instruction narrowing. This patch adds the missing check.

Sergey Kaplun:
* added the description and the test for the problem

Part of tarantool/tarantool#10199
