Priyanshu Thapliyal daf2cb8bfd avcodec/alsdec: fix abs(INT_MIN) UB in read_diff_float_data()
Replace abs() with FFABSU() to avoid undefined behavior when
raw_samples[c][i] == INT_MIN. Per libavutil/common.h, FFABS()
has the same INT_MIN UB as abs(); FFABSU() is the correct
helper as it casts to unsigned before negation.
