repair: Always use run_replace_ops
repair: Always use run_replace_ops

Currently, the new NODE_OPS_CMD for replace operation is used only when
repair based node operation is enabled. However, We can use the
NODE_OPS_CMD to run replace operation and use streaming instead of
repair to sync data as well.

After this patch, we will use streaming inside run_replace_ops if repair
based node ops is not enabled. So that we can take the benefits that
NODE_OPS_CMD brings in commit 323f72e48a7d89d9edc40257a1f45c202accc146
(repair: Switch to use NODE_OPS_CMD for replace operation).

Fixes #8013
