avcodec/exr: Avoid signed overflow in displayWindow
The inputs are unused except for this computation so wraparound
does not give an attacker any extra values as they are already fully
controlled
Fixes: signed integer overflow: 0 - -2147483648 cannot be represented in type 'int'
Fixes: 45820/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_EXR_fuzzer-5766159019933696
