Using existing names to display extent counts would require an xfs_db user to
additionally check the status of XFS_DIFLAG2_NREXT64 flag in order to
determine the exact source of the extent count (large extent counter vs small
extent counter).
This was the reason to print the large extent counters with different field
names.
Come to think of it, Most of the times an xfs_db user would generally be
interested in the extent counter value rather than the exact field from which
the count has been obtained from. Hence in the interest of optimizing for the
general case, I will change the code to continue to use nextents/naextents
names.

Actually xfs/298 is the only test which refers to nextents field directly,
_scratch_xfs_db -c "inode $inode" -c "p core.nextents"
Other tests use the helper function _scratch_get_iext_count() to obtain the
value of extent counters.
I had extended _scratch_get_iext_count() to obtain the correct data/attr fork
extent counters based on whether the per-inode flag XFS_DIFLAG2_NREXT64 is set
or not. This won't be required when xfs_db uses the same names to print the
extent counters.
