Subject: [PATCH 1/2] Fixed loopback device to emit uevent on auto release

At Andrew Norton's request, I've split up my API cleanup patches into two.
Below is Phillip Susi's uevent notification fix and the second part of the
patch is the API cleanup.

Subject: [PATCH 1/2] Fixed loopback device to emit uevent on auto release

The loopback driver failed to emit the change uevent
when auto releasing the device.  Fixed lo_release()
to pass the bdev to loop_clr_fd() so it can emit
the event.
