media: uvcvideo: Invert default value for nodrop module param

Browse Source 
The module param `nodrop` defines what to do with frames that contain an
error: drop them or sending them to userspace.

The default in the rest of the media subsystem is to return buffers with
an error to userspace with V4L2_BUF_FLAG_ERROR set in v4l2_buffer.flags.
In UVC we drop buffers with errors by default.

Change the default behaviour of uvcvideo to match the rest of the
drivers and maybe get rid of the module parameter in the future.
