mshtml: Set outgoing pass-by-address variable in an error case case within confirm_safety_load.

[Gerald Pfeifer]

I noticed we return in this case, without initializing this variable.
Visual inspection indicates we do not seem to access the variable in
this error case, but a) better safe than sorry, and b) GCC 4.8 currently
warns about it.

Not sure URLPOLICY_DISALLOW is the best return value, open for better
alternatives.
