Currently doing 'reset' command in sandbox with tracing enabled causes
SIGSEV
```
Hit any key to stop autoboot: 0
=>
=>
=> reset
resetting ...
Segmentation fault (core dumped)
```
Tracing callback uses RAM buffer for storing tracing reports, but
state_uninit() function unmaps whole RAM, which causes SIGSEV on umapped
memory inside tracing subsystem.
Fix it by disabling tracing before unmapping memory
