PCI/MSI: Correct misleading comments
commit
689e6b5351573c38ccf92a0dd8b3e2c2241e4aff upstream.
The comments about preserving the cached state in pci_msi[x]_shutdown() are
misleading as the MSI descriptors are freed right after those functions
return. So there is nothing to restore. Preparatory change.
