Summary: SSL crash interpreter on error

Initial Comment:
When testing bug 739909, I provoked this bug.  To
reproduce:

  # ./python # need to be root to listen on privileged port
  >>> from socket import *
  >>> s = socket(AF_INET, SOCK_STREAM)
  >>> s.bind(('', 993))
  >>> s.listen(5)
  >>> s.accept()

  # now go to another window and do:

  $ ./python
  >>> import imaplib
  >>> imaplib.IMAP4_SSL('localhost')

  # this will wait for the first (root) interpreter
  # exit from first/root interpreter and SSL will crash

There is a stack trace below.

The problem is that in PySSL_SetError(), there is an
assumption that obj->Socket exists, but it doesn't in
this case.

The attached patch  fixes the crash, but I'm not
certain it is correct.
