x86: pvclock: Add flag to indicate that a vm was stopped by the host

This flag will be used to check if the vm was stopped by the host when a soft
lockup was detected. The host will set the flag when it stops the guest. On
resume, the guest will check this flag if a soft lockup is detected and skip
issuing the warning.
