transfer: fix retry for empty downloads on reuse
When a reused connection did transfer 0 bytes, it assumed the transfer
had failed and needed a retry. Add a check for data->red.done, so we can
successfully accept the transfer of a 0-length file via SFTP.

Add test case 1583 to verfiy.

Fix SFTP disconnect debug trace when there was nothing to
disconnect (like when reusing a connection).

Fixes #19165
