secur32: Fix wrapper.c to honour functions that are run twice.

[Kai Blin]

Fixed the wrapper calls to InitializeSecurityContext(A/W) and
AcceptSecurityContext to correctly handle SEC_I_CONTINUE_NEEDED returns.

Corrected writing the wrapped context to the correct variable.

Corrected InitializeSecurityContext(A/W)'s and AcceptSecurityContext's
calls to unwrap the context before passing it to the package's
functions.

Changelog:
Kai Blin <blin at gmx.net>
Fixed a couple of bugs in InitializeSecurityContext(A/W) and 
AcceptSecurityContext.
