[media] em28xx-v4l: get rid of field "users" in struct em28xx_v4l2"
This reverts commit 747dba7de2a51a3db58b665ed3bc8c07921546ec.
It breaks concurrent vbi and video capturing:
While v4l2->users is the number of users of the whole device (all device nodes),
v4l2_fh_is_singular() only checks the number of users of a specific device node.
As a result. if one device node is open and a second device node is opened
(closed), the device is reinitialized (streaming is stopped).
