ext4: remove unused EXT_STATS macro from ext4_extents.h

The EXT_STATS macro in fs/ext4/ext4_extents.h has been defined
but never used in the codebase since its introduction. This patch
removes it.

Analysis:
1. No references found in fs/ext4/ or other kernel code.
2. No impact on compilation or functionality.
3. Git history shows it was never utilized.
