Ondrej Mosnacek 6a1afffb08 selinux: fix NULL dereference in policydb_destroy() ... The conversion to kvmalloc() forgot to account for the possibility that p->type_attr_map_array might be null in policydb_destroy(). Fix this by destroying its contents only if it is not NULL. Also make sure ebitmap_init() is called on all entries before policydb_destroy() can be called. Right now this is a no-op, because both kvcalloc() and ebitmap_init() just zero out the whole struct, but let's rather not rely on a specific implementation.
