USB: fixup for merge issue with "usb: dwc3: Don't switch OTG -> peripheral if extcon is present"

Today's linux-next merge of the extcon tree got a conflict in:

  drivers/usb/dwc3/drd.c

between commit:

  0f010171 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present")

from the usb tree and commit:

  88490c7f43c4 ("extcon: Fix extcon_get_extcon_dev() error handling")

from the extcon tree.

I fixed it up (the former moved the code modified by the latter, so I
used the former version of this files and added the following merge fix
patch) and can carry the fix as necessary.
