Remove Delock 87445 from supported list

According to report from @vkahl: #123,
Delock 87445 is not detected on various Linux systems.

Originally this hub was reported to work in #107.
I don't know if there were different hardware revisions of Delock 87445,
but it is safer to remove it from supported devices list until proven otherwise.

Also, I am skeptical that it will work correctly as it does not have external power supply.
