[FFmpeg-devel] [PATCH] dnn_backend_native_layer_conv2d.c: fix bug of loop boundary in single thread mode.

[xujunzz at sjtu.edu.cn]

From: Xu Jun <xujunzz at sjtu.edu.cn>

Before patch, fate test for dnn may fail in some Windows environment
while succeed in my Linux. The bug was caused by a wrong loop boundary.
Win10 and Linux seems to have different explaination for that.After
patch, fate test succeed in my windows mingw 64-bit.
