pidgin/pidgin

Fix a crash in the wincred providered when adding a password.

Something about the way the freeing works on Windows causes a segfault if we memset the memory to 0 first.

Testing Done:
Created a new account, stored the password, verified it was in the Credential Manager and that Pidgin didn't crash.
