Based on https://docs.nvidia.com/grid/index.html and the driver you mentioned at the top (nvidia-vgpu-ubuntu-525_525.85.07_amd64.deb) you are running driver version 15.1.
Thus, I think I can conclude that the nova-compute-nvidia-vgpu charm doesn't fully setup that version of the software, hence your need to perform the manual step.
For future travellers:
* The charm ought to detect the version of the nvidia payload software and display a warning on the status line if it doesn't officially support that version: aka it hasn't actually been tested with it.
* To manually fix, use the sriov-manage command to initialise the driver completely.
