clang-tidy was warning:
```
util/env.c:334:23: warning: Access to field 'nr_pmu_mappings' results in a dereference of a null pointer (loaded from variable 'env') [clang-analyzer-core.NullDereference]
env->nr_pmu_mappings = pmu_num;
```
As functions are called potentially when !env was true. This condition
could never be true as it would produce a segv, so remove the
unnecessary NULL tests and silence clang-tidy.
