What does "smear out" mean in the following sentence? I didn't find it in any dictionary.

However, small though the length is, it is nevertheless finite, and this finite extent is the bridge between quantum theory and general relativity in that it smears out the quantum fluctuations

It means that this is the length-scale at which quantum fluctuations are no longer relevant. What you would "see" above this length-scale is the net effect of many smaller quantum effects combined, so you see them "smeared" together.
