camera: avoid narrowing of the ioctl request

The `ioctl` take request of the `unsinged long` type but current
implementation narrows it up to `int`.

Test: if add something like this into `IoctlLocked`:
      ```
      switch (request) {
        case VIDIOC_QBUF: break;
        default:;
      }
      ```
      the following error is appears: "error: case value evaluates
      to 3227014671, which cannot be narrowed to type 'int'
      [-Wc++11-narrowing]".
