Warning: newbie user-submitted patch attached for your consideration.
Attempting to use git send-email as requested.  

Reference Thread: 
"avcodec/nvenc: multiple reference frames support"
http://ffmpeg.org/pipermail/ffmpeg-devel/2019-October/251611.html

Context: https://trac.ffmpeg.org/ticket/8254 
The option -refs works OK on newest models of nvidia graphics cards
however fails with a slightly obscure (to a user) error message on 
common but lesser models of nvidia graphics cards (eg 1050Ti).

The attached patch seeks to slightly modify relevant error messages
and change error messages in nvenc_check_capabilities to be issued
as warnings instead of verbose.

Thank you for considering the patch.
