hv: ptdev: refine look up MSI ptirq entry

Browse Source 
There's no need to look up MSI ptirq entry by virtual SID any more since the MSI
ptirq entry would be removed before the device is assigned to a VM.

Now the logic of MSI interrupt remap could simplify as:
1. Add the MSI interrupt remap first;
2. If step is already done, just do the remap part.
