Alek P 931deb290c Prevent range tree corruption race by updating dnode_sync() 
Switch to incremental range tree processing in dnode_sync() to avoid
unsafe lock dropping during zfs_range_tree_walk(). This also ensures
the free ranges remain visible to dnode_block_freed() throughout the
sync process, preventing potential stale data reads.

This patch:
 - Keeps the range tree attached during processing for visibility.
 - Processes segments one-by-one by restarting from the tree head.
 - Uses zfs_range_tree_clear() to safely handle ranges that may have
   been modified while the lock was dropped.
 - adds ASSERT()s to document that we don't expect dn_free_ranges
   modification outside of sync context.
