Log Message:
Another contribution to PR kern/42225 which will hopefully
bring the story to an end:

Always ignore the residue from the CSW, just use the real
transfer length counted by the USB stack. This was first
proposed by Markus Kilbinger but unfortunately ignored
later. (Too many cooks...)
According to Matthias Kretschmer, Darwin and Haiku do
the same.

Remove the "UMASS_QUIRK_IGNORE_RESIDUE" quirk which was
just for the one "SuperTop" device mentioned in the PR.
This device was successfully tested by Matthias Kretschmer /
Ignatios Souvatzis.

I've tested the patch with various other devices and
didn't find regressions.
