 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.
