media: pvrusb2: fix memory leak in pvr_probe
commit 945a9a8e448b65bec055d37eba58f711b39f66f0 upstream.
The error handling code in pvr2_hdw_create forgets to unregister the
v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create,
it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,
which leads to that pvr2_hdw_destroy directly returns.
Fix this by adding v4l2_device_unregister to decrease the refcount of
usb interface.
