media: v4l2-core: Remove BUG() from i2c and spi helpers
Currently, the i2c and spi subdev creation helpers are calling BUG() when passed a NULL v4l2_device parameter. This makes little sense; simply returning NULL seems more sensible. These two helpers may already return NULL on error, so callers should already be checking for this, or at least be prepared for a NULL result.
