Fix for `pallet_assets::create` benchmark

[bkontur]

Benchmark for create should use origin returned by T::CreateOrigin::try_successful_origin instead of SystemOrigin::Signed(caller).

E.g. ForeignCreators does not work with that, because it expects PalletXcm::Origin which is correctly returned from T::CreateOrigin but then caller is wrapped with SystemOrigin::signed(caller) which does not pass EnsureXcm validation here
