app/vmselect: fix panic/incorrect tenant in key

Browse source 
This is a follow-up after 3120dc2
  
- Consistently use key for rollupCache in multitenant mode cache keys use different authTokens. Previously it could lead to panic in rare cases when cache state was inconsistent. 
- Do not share `err` variable across goroutines for `processBlock` function. It could lead to data races.

* BUGFIX: [vmsingle](https://docs.victoriametrics.com/single-server-victoriametrics/), `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): properly return result for binary operation `^` aka pow at query requests for `NaN` values. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7359) for details.
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix rendering of isolated data points on the graph that are not connected to other points.
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert): improve the correctness of alert [state restoration](https://docs.victoriametrics.com/vmalert/#alerts-state-on-restarts). Previously, it could result in false-positive alerts if alert was resolved shortly before vmalert restart.
* BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): Properly handle [multitenant](https://docs.victoriametrics.com/cluster-victoriametrics/#multitenancy-via-labels) query request errors and correctly perform search for available tenants. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7549) for details.
