Commit 201e0d53bd ("stub: split out random seed part out of run()")
looks like refactoring but apparently it changed the logic when random
seed is refreshed in the ESP completely. Previously, process_random_seed()
was called when either:
- sd-stub was not present (LoaderFeatures var is unset) OR
- sd-stub was present but EFI_LOADER_FEATURE_RANDOM_SEED flag was unset.
Post-change, refresh_random_seed() bails under the exact same conditions (no
sd-stub or EFI_LOADER_FEATURE_RANDOM_SEED is unset) and thus
process_random_seed() is NOT called.
Restore the original logic. efivar_get_uint64_le()'s return value doesn't
require checking: loader_features is initialized to 0 and in case of failure it
stays untouched.
