sftp: Use the data connection when pushing data
sftp: Use the data connection when pushing data

Use the newly-introduced data connection when pushing data from a sftp
mount. This prevents blocking other operations behind a few MBs of
in-flight data and improves interactivity.

If the data connection is not usable, fall back to the default copy
implementation.
