Clang's static analyzer complains about a possible NULL pointer dereference in nvlist_lookup_nvpair_ei_sep() because it unconditionally dereferences a pointer initialized by `nvpair_value_nvlist_array()` under the assumption that `nvpair_value_nvlist_array()` will always initialize the pointer without checking to see if an error was returned to indicate otherwise. This itself is improper error handling, so we fix it. However, fixing it to properly respond to errors is not enough to avoid a NULL pointer dereference, since we can receive NULL when the array is empty, so we also add a NULL check.
