Dereference before null check

There may be a null pointer dereference, or else the comparison against null is unnecessary. All paths that lead to this null pointer comparison already dereference the pointer earlier
/src/mongo/db/catalog/index_consistency.cpp:757: REVERSE_INULL 149655 Dereferencing pointer "results". [Note: The source code implementation of the function has been overridden by a builtin model.]
/src/mongo/db/catalog/index_consistency.cpp:855: REVERSE_INULL 149655 Null-checking "results" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
