Commit Message

Fix limit check in narrow_conv_backprop().

Thanks to Sergey Kaplun.

(cherry picked from commit e45fd4cb7)

`narrow_conv_backprop()` misses the stack pointer (`nc->sp`) limit check
after a bunch of recursive calls that may change its value. As a result,
it leads to stack-buffer-overflow during the instruction narrowing. This
patch adds a missing check.

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