[PATCH 1/6] usb: core: add missing pm_runtime_dont_use_autosuspend() call

[Joshua Crofts <joshua.crofts1@gmail.com>]

The fail label in usb_new_device() disables pm_runtime on failure, but
doesn't call pm_runtime_dont_use_autosuspend(), causing resource leaks.

Add the missing pm_runtime_dont_use_autosuspend() call.

Found using Coccinelle.
