pblock->nNonce = 0 will result in a nullptr dereference if the added assertion does not hold true.

pblock != nullptr is not obvious from reading the code - hence the need for stating this assumption explicitly via an assertion. This has the added benefit getting rid of the following clang-tidy warning:
```
rpc/mining.cpp:560:20: note: Access to field 'nNonce' results in
  a dereference of a null pointer (loaded from variable 'pblock')
    pblock->nNonce = 0;
```

Anyone willing to review? :-)
