[IA64] Don't perform implicit sync when vps_save/restore

When calling vps_save/restore, pass 1 as the third parameter not to
perform implicit sync.

The third parameter of vps_save/restore is used to indidate whether
vps_save/restore do implicit vps_read_sync/vps_write_sync.
When the third parameter is 1, it doesn't perform implicit sync.
This parameter adds flexibility of vps_save/restore.
This feature was newly introduced by SDM specification update June 2008.
