mshtml/tests: Fix SysFreeString call with wrong variable.

[Rico Schüller]

Hi,

I'd like to have some feedback, before I send this to wine-patches.

This patch removes a regression in the mshtml test, where the wrong 
variable is called by SysFreeString, which leads sometimes to a crash ( 
http://test.winehq.org/data/0d7bec3578e02e1f551813e86100b59e36aec542/#group_... 
).

Is this fix correct?

A second problem is there a need to call SysFreeString() after each 
IHTMLStyle_get* when a variable isn't used any more because it does a 
Sys*AllocString* call (in get_nsstyle_attr)? Or is this call useless and 
automatically done when the app is terminated?

Cheers
Rico

Yes, it is.

It is not useless, although the memory is freed after app terminated, we 
should free it as soon as it's no longer needed.
