ext4: drop extent cache when splitting extent fails

Browse source

commit 79b592e8f1 upstream.

When the split extent fails, we might leave some extents still being
processed and return an error directly, which will result in stale
extent entries remaining in the extent status tree. So drop all of the
remaining potentially stale extents if the splitting fails.
