CVS commit: src/sys/dev

["matthew green" <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg
Date:           Tue Sep 18 05:24:10 UTC 2018

Modified Files:
        src/sys/dev/pci: xhci_pci.c
        src/sys/dev/usb: usb.c

Log Message:
deal with partial attach failures in usb_attach vs usb_detach aka PR 53598.

- make sure xhci's sc->sc_ios is NULL if failure happens.
- rearrange usb_attach() / usb_doattach() to make it simpler to clean up.
- move usb_async_intr softint into usb_once_init().  previously, each USB
  controller would start a new one, and leave the old one leaked.
- handle controller interrupts without a bus attached
