[Qemu-devel] [PULL 9/9] usb: remove unnecessary NULL device check from usb_ep_get()

[Gerd Hoffmann <kraxel@redhat.com>]

From: Liam Merwick <liam.merwick@oracle.com>

No caller of usb_ep_get() calls it with a NULL device (previous commits
have addressed the few remaining cases which didn't explicitly check).
Replace check for 'dev == NULL' with an assert instead.
