test/nvmf: improve nested lvol test 



Nested lvolstores take a very long time to create,
since the initial unmap will get broken into
one unmap per cluster for the underlying lvol.

This test is working fine in the test pool, but they
have much smaller SSDs.  My system has a 3.7TB SSD,
and this test times out.

So don't bother clearing the nested lvol store - this
saves unmap operations.  We still have unmap operations
when deleting the nested lvol, so increase the cluster
size for the main lvolstore to 1GiB to reduce the total
number of unmap operations.
