V4L/DVB (8894): pvrusb2: Remove BKL
The earlier change from Hans Verkuil that pushed the BKL from video_open() down into the drivers should be unneeded for the pvrusb2 driver. This driver's implementation for open already protects its internal structures through other means, thus the BKL is not required. This change reverses Hans' previous change, for the pvrusb2 driver. It probably would have been a good idea for Hans to previously have asked for my ack before committing his change.
