ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Wed Jul  7 16:43:03 2021 +0200| [fdc0bb78feb7a4684dd958d2538a0974c12b12cd] | committer: Anton Khirnov

lavu/slicethread: return ENOSYS rather than EINVAL in the dummy func

EINVAL is the wrong error code here, since the arguments passed to the
function are valid. The error is that the function is not implemented in
the build, which corresponds to ENOSYS.
