[RSAENH] CPEncrypt / Bug 5639

[Karsten Elfenbein]

Hi,

I wonder if the attached patche would make in into git?

It fixes the case when CryptEncrypt is called with pbData=NULL to
determine
the needed buffer size after encryption.

It fixes the http://bugs.winehq.org/attachment.cgi?id=3023&action=view
testcase in http://bugs.winehq.org/show_bug.cgi?id=5639
