csi: correct conditional logic for fuse mount options argument

Previously, the function incorrectly checked if `len(options) == 0`,
causing it to return a non-empty argument when no options were provided.
This fix updates the condition to `len(options) > 0`, ensuring the argument
is only set when options exist.
