TagLib::ASF::Tag::addAttribute possible memory leakage?

[Anthony Liu]

Hello.

The memory leakage occurred only when my application wrote asf tag, the
tagreader works normally.

When I write some text attributes, the memory usage is stable, however when
I add some "BIG" size album art attributes(e.g from some pictures whose size
is over 1MB), it increased significantly.

I think the bug always exists, but only noticeable when you add some big
attributes.
