[XFS] Warn if errors come from block_truncate_page().
block_truncate_page() can return errors that we currently ignore and silently discard. We should not ever get errors reported here - an error indicates a bug somewhere else. Hence catch the error and issue a stack dump to the syslog because we cannot propagate the error any further up the call chain.
