Aparna Das ad3b170f43 gpu: nvgpu: vgpu: ring doorbell after enabling TSG ...

In some use cases client will disable and preempt TSG and then re-enable it
using IOCTLs provided

In case there is only one context getting re-enabled and there is no other job
submission in parallel runlist fetcher will just sleep until doorbell is
received next time

This causes above mentioned test cases to stall after re-enabling TSG
until some one submits a new job and triggers a doorbell

Fix this by explicitly triggering doorbell in vgpu code
after we enable all channels in TSG.
