[FFmpeg-cvslog] lavfi/vf_srcnn: use avio_check instead of access

[Hendrik Leppkes]

ffmpeg | branch: master | Hendrik Leppkes <h.leppkes at gmail.com> | Tue May  8 17:25:26 2018 +0200| [8007a86363930353a9df0007432fae73fc817dda] | committer: Hendrik Leppkes

lavfi/vf_srcnn: use avio_check instead of access

The filter uses avio for file access already, and avio_check is
portable.

Fixes trac #7192.
