ext4: fix error handling in ext4_ext_truncate()
commit 8acd5e9b upstream. Previously ext4_ext_truncate() was ignoring potential error returns from ext4_es_remove_extent() and ext4_ext_remove_space(). This can lead to the on-diks extent tree and the extent status tree cache getting out of sync, which is particuarlly bad, and can lead to file system corruption and potential data loss.
