avfilter/vf_yadif: fix extra leading dup frame when deint=1
Logic for handling single frame in yadif (0f9f24c9), caused deint=1 (e.g., yadif=0:-1:1) to output extra duplicate leading frame:
ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf yadif=0:-1:1,showinfo -f null -y /dev/null
[Parsed_showinfo_1 @ 0x1d967d0] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]

(Outputs 51 frames)
After patch, vf "yadif=0:-1:1" behaves correctly (like "yadif=0:-1:0") and outputs 50 frames, first two:

(Outputs 50 frames)
