[issue44285] Coverity scan: Modules/getpath.c. "calculate_open_pyenv" allocates memory that is stored into "env_file".

New submission from Charalampos Stratakis <cstratak at redhat.com>:

This is an issue as it seems with coverity as it's an error case where the file was not actually opened. This warning can be silenced and the code be made more explicit by adding an assertion.

Python-3.9.1/Modules/getpath.c:1264: alloc_arg: "calculate_open_pyenv" allocates memory that is stored into "env_file".
Python-3.9.1/Modules/getpath.c:1266: leaked_storage: Variable "env_file" going out of scope leaks the storage it points to.
# 1264|       status = calculate_open_pyenv(calculate, &env_file);
# 1265|       if (_PyStatus_EXCEPTION(status)) {
# 1266|->         return status;
# 1267|       }
# 1268|       if (env_file == NULL) {
