USB: fixes for v4.20-rc4

In this second set of fixes for the current -rc cycle, we have some
regressions fixes for the old omap_udc driver done by Aaro Koskinen.

We're also reverting an old patch on dwc3 which is, now, known to
break USB certification in some cases.

We have a fix on u_ether for an unsafe list iteration.
