Max Reitz c64c3ae35b iotests: Disable 110 for vmdk.twoGbMaxExtentSparse
The error message for the test case where we have a quorum node for
which no directory name can be generated is different: For
twoGbMaxExtentSparse, it complains that it cannot open the extent file.
For other (sub)formats, it just notes that it cannot determine the
backing file path.  Both are fine, but just disable twoGbMaxExtentSparse
for simplicity's sake.
