usb: fixes for v3.17-rc4 

Some late fixes for dwc3 so we have something more stable
 on v3.17-final.
 
 Most bugs have been there for quite a while and nobody
 noticed, except for TRB completion when multiple TRBs
 are started.
 
 Patches were tested on AM437x SK and J6 EVM and are passing
 my tests.
