Description

get_features() does some work to parse RBD_FEATURES from the environment if supplied, but if not, it sets *old_format to true...but doesn't set *features at all, and some of its callers then refer to features. This causes tests to fail on arm64, where the stack garbage presumably is different.

set *features to 0 if RBD_FEATURES is not found in the env.
