bugfix: fixed a bug of the fiber status call

Fixed a bug of the fiber status call when
processing `RELOAD_SCHEMA_TIMEOUT` in `call_reload_schema`.
Before that, an error occurred in this case with description:
`calling 'status' on bad self (fiber expected, got table)`.
To reproduce the error before this fix, it is enough to
checkout to the one commit back and perform the action
described in #331.
Now the fibers for schema reloading are correctly canceled
if the timeout on schema reloading is reached.
