wusa: Zero out identity on error path in read_identity.

Fixes double frees in read_components and read_dependency. The double frees could also be fixed by using free instead of free_dependency in those functions, but zeroing out the pointers is easier to understand because it ensures that alloc_dependency can always be paired with free_dependency.
