As is done in zram_rw_page, pmem_rw_page, and btt_rw_page, don't
call page_endio in the error case since do_mpage_readpage and
__mpage_writepage will resubmit on error. Calling page_endio in the
error case leads to double completion.

If our device loses its connection for longer than the dead timeout we
will set NBD_DISCONNECTED in order to quickly fail any pending IO's that
flood in after the IO's that were waiting during the dead timer.
However if we re-connect at some point in the future we'll still see
