liujunming ffd13a2fe1 hv: vpci: fix msi enable issue under some cases ...

In VT-d scenario, if MSI interrupt has been enabled,
vCPU writes the content in MSI registers,
and all bits of the content are read-only.

In this case, hypervisor code will call
enable_disable_msi(vdev, false), which will disable MSI.
And there's no chance to call remap_vmsi.
This is wrong behavior, which will result in the disable of MSI.

Tracked-On: #5847
