Bug Description

SRU Justification

[Impact]

Upstream stable patchset 2022-01-19 (LP: #1958461) as applied to linux-aws-5.11 5.11.0-1029.32_20.04.1 causes a boot regression.

[Fix]

Revert commit caefebc4b66f841612504c9bb3b37ce6a326d994 ("PCI/MSI: Mask MSI-X vectors only on success")

[Test Case]

Install a kernel in a Focal/aws c4.large instance.

[Where things could go wrong]

Other instance types could fail without this patch, though it is unlikely.
