example/memfs_ll: Avoid nullptr field initializations by pragma

These nullptr initializations don't make sense - methods that
are not explicitly set are not implemented. I thought that C++20
would eventually avoid the nullptr, but looks like compilers
still give warnings - avoid them with a pragma.
