Streams do not work reliabe on Fresco Logic FL1000G xhci controllers,
trying to use them results in errors like this:
21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled
endpoint or incorrect stream ring
21:37:33 kernel: xhci_hcd 0000:04:00.0: @00000000368b3570 9067b000 00000000
05000000 01078001
21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled

05000000 01038001
As always I've ordered a pci-e addon card with a Fresco Logic controller for
myself to see if I can come up with a better fix then the big hammer, in
the mean time this will make uas devices work again (in usb-storage mode)
for FL1000G users.
