Restart video when mode detection is failed
KVM sometimes stops when video mode is changed. This commit adds
video restarting logic for the case.
Tested:
1. Open BMCWeb -> Server control -> KVM
2. Checked KVM screen update while restarting the host. It
updates all frames even when video mode changes happen.
