Now that in the error patch of extent updating procedure cannot handle
error and roll-back partial updates properly, so we could access the
left inconsistent extent buffer later and lead to BUGON in
errors=continue mode. For example, we could get below BUGON if we
update leaf extent but failed to update index extent in
ext4_ext_insert_extent() and try to alloc block again.
