Urvang Joshi 03f6fdcfca Fix warnings reported by -Wshadow: Part1b: scan_order struct and variable
- Change struct name to all caps SCAN_ORDER to be locally consistent.
- Rename struct pointers to 'scan_order' instead of hard to read short
  names 'so' and 'sc'.

Cherry-picked from aomedia/master: 30abc082
