net/mlx4_core: Use ARRAY_SIZE macro
Use ARRAY_SIZE macro, rather than explicitly coding some variant of it yourself. Found with: find -type f -name "*.c" -o -name "*.h" | xargs perl -p -i -e 's/\bsizeof\s*\(\s*(\w+)\s*\)\s*\ /\s*sizeof\s*\(\s*\1\s*\[\s*0\s*\]\s*\) /ARRAY_SIZE(\1)/g' and manual check/verification.
