From: Hyman Huang <yong.huang@smartx.com>

The global static variable ram_state in fact is referred to by the
"rs" parameter in migration_bitmap_sync_precopy. For ease of calling
by the callees, use the global variable directly in
migration_bitmap_sync_precopy and remove "rs" parameter.

The migration_bitmap_sync_precopy will be exported in the next commit.
