81ba70a497 pci, vmm: Defer mapping VFIO MMIO regions on restore 
When restoring a VM, the restore codepath will take care of mapping the
MMIO regions based on the information from the snapshot, rather than
having the mapping being performed during device creation.

When the device is created, information such as which BARs contain the
MSI-X tables are missing, preventing to perform the mapping of the MMIO
regions.

65dc1c83a9 vmm: cpu: Save and restore CPU states during snapshot/restore 
Based on recent KVM host patches (merged in Linux 5.16), it's forbidden
to call into KVM_SET_CPUID2 after the first successful KVM_RUN returned.
That means saving CPU states during the pause sequence, and restoring
these states during the resume sequence will not work with the current
design starting with kernel version 5.16.

In order to solve this problem, let's simply move the save/restore logic
to the snapshot/restore sequences rather than the pause/resume ones.
