SOLOFusion with python3.7.10, torch1.9, cudatoolkit 11.1 bug fixed

[MalignusCN]

Hi Divadi, I've found that execute SOLOFusion project with python3.7.10, torch1.9, cudatoolkit 11.1 as your project mentioned, there is a small bug.

mmdet3d/models/necks/view_transformer_solofusion.py
meshgrid = torch.stack(torch.meshgrid(torch.arange(stereo_W), torch.arange(stereo_H), indexing="xy"), dim=2)
should changed as
meshgrid = torch.stack(torch.meshgrid(torch.arange(stereo_H), torch.arange(stereo_W)), dim=2)

which is mainly because pytorch with version 1.9, the meshgrid method didn't support indexing. The problem further results in the reverse of stereo_H and stereo_W, hope that can help other people
