x86/MSI: fix 2nd S3 resume with interrupt remapping enabled

The first resume from S3 was corrupting internal data structures (in
that pci_restore_msi_state() updated the globally stored MSI message
from traditional to interrupt remapped format, which would then be
translated a second time during the second resume, breaking interrupt
delivery).
