SRU Justification
[Impact]
Recent additions to focal/azure to support multi-MSI on the Azure hypervisor break fio tests on NVMe disks.
The initial fix is to revert the 4 patches.
06ad0de407e7ab357f5be5c0dc2290e39ddbf936 PCI: hv: Fix interrupt mapping for multi-MSI
6f7265bdd6161702cc1530ce7a2d126c49977d3d PCI: hv: Reuse existing IRTE allocation in compose_msi_msg()
c6a7a02229c2acd4e19602f7b2fcd95ea163eada PCI: hv: Fix hv_arch_irq_unmask() for multi-MSI
9dc3b7f1d164efda04c4756002011e2ddc9f1c73 PCI: hv: Fix multi-MSI to allow more than one MSI vector
[Where things could go wrong]
Focal will not have support for multi-MSI, but since this is such a new feature there is likely little consequence.
