KVM: SEV: Lock all vCPUs for the duration of SEV-ES VMSA synchronization

Browse source

Lock and unlock all vCPUs in a single batch when synchronizing SEV-ES VMSAs
during launch finish, partly to dedup the code by a tiny amount, but mostly
so that sev_launch_update_vmsa() uses the same logic/flow as all other SEV
ioctls that lock all vCPUs.
