Robert Kubiś 68906658fd ftp: fix ranged reads failing when the server answers 425 to an early close - Fixes #10200 ...

A ranged read through the VFS opens the object at offset 0 and then
seeks, so the first RETR is closed before anything was read. Egnyte
answers that close with 425 instead of 426.

425 was not masked, so ftpReadCloser.Close quit the connection and
returned an error. The VFS then retried and closed the same reader
again; the second Close got nil from the already closed response, put
the connection that had been quit back in the pool and returned its
token a second time. Later operations failed with "use of closed
network connection" and serve s3 returned InternalError.

Now a second Close does nothing, a connection is never pooled after
Quit, and 425 is masked only when nothing was read, so a transfer cut
after data was read is still an error.
