migration/savevm: remove duplicate check of migration_is_blocked 

Current call flow of save_snapshot is:

  save_snapshot
    migration_is_blocked
      qemu_savevm_state
        migration_is_blocked

Since qemu_savevm_state is only called in save_snapshot, this means
migration_is_blocked has been already checked.
