This reverts commit 3804fad45411b48233b48003e33a78f290d227c8.

This commit, together with commit 247bf557273dd775505fb9240d2d152f4f20d304
"xhci 1.0: Limit arbitrarily-aligned scatter gather." were
origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices
working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer
buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass
storage devices to fail more frequently.

USB 3.0 mass storage devices used to work before 3.14-rc1.  Theoretically,
the TD fragment rules could have caused an occasional disk glitch.
Now the devices *will* fail, instead of theoretically failing.
>From a user perspective, this looks like a regression; the USB device obviously
fails on 3.14-rc1, and may sometimes silently fail on prior kernels.

The proper soluition is to implement the TD fragment rules for xHCI 1.0 hosts,
but for now, revert this patch until scatter gather can be properly supported.
