media: uvcvideo: Use a count variable for meta_formats instead of 0 terminating

The code dealing with the 0 terminated meta_formats array is a bit klunky
especially for the uvc_meta_v4l2_enum_formats() case.

Instead of 0 terminating add an unsigned int nmeta_formats member to struct
uvc_device and use that. This leads to slightly cleaner code.
