[PATCH] transport: report missing submodule pushes consistently on stderr

[Stefan Beller <sbeller@google.com>]

The surrounding advice is printed to stderr, but the list of submodules
is not. Make the report consistent by reporting everything to stderr.

  This fixes one of the bugs mentioned in
  https://public-inbox.org/git/CAGZ79kbkyupBJfvyX3Hj_R5ZW36+3ufOnnLC-Dpic40nPJAxDA@mail.gmail.com/T/#t
  
  How to fix the other was not as obvious to me as I do not understand the
  philosophy on verbosity in the transport code.
  
  Thanks,
  Stefan
