Subject: [PATCH v3 06/15] [media] vivid: assign the specific device to the vb2_queue->dev

From: Gustavo Padovan <gustavo.padovan@...labora.com>

Instead of assigning the global v4l2 device, assign the specific device.
This was causing trouble when using using V4L2 events with vivid
devices. The device's queue should be the same we opened in userspace.

This is needed for the upcoming V4L2_EVENT_BUF_QUEUED support. The current
vivid code isn't wrong, it just needs to be changed so V4L2_EVENT_BUF_QUEUED
can be supported. The change doesn't affect any other behaviour of vivid.
