x86/pvclock: Zero last_value on resume
commit e7a3481c0246c8e45e79c629efd63b168e91fcda upstream.
If the guest domain has been suspend/resumed or migrated, then the
system clock backing the pvclock clocksource may revert to a smaller
value (ie, can be non-monotonic across the migration/save-restore).
Make sure we zero last_value in that case so that the domain
continues to see clock updates.
