MSHTML: Fix comment about hack

[Jacek Caban]

Alexandre, thanks for implementing SetDllDirectory.
Unfortunatelly, in contrast to my comment in patch,
we can't use it for loading Gecko as it could affect
other applications. I've checked that the Gecko dir has
to remain on the path, so we cannot set it at the time
of loading XPCOM and restore it after, in contrast to
what I had previously expected.
