Avoid memory leak if xmlParserInputBufferCreateIO fails

Browse Source 
For https://bugzilla.gnome.org/show_bug.cgi?id=643949

In case of error on an IO creation input the given context
is terminated with the given close function, except if the
error happened in xmlParserInputBufferCreateIO. This can
lead to a resource leak which is fixed by this patch.
