The current test case attempts to create a state to read
by calling setattr and getattr in attempt to force block
cache reads. It so happens that this does not always force
cache block reads, which in rare cases causes this test case
to fail.
The new test case removes all the extra bouncing around of mount
points and we just directly call scoutfs df which will walk
everyone's allocators to summarize the block counts, which is
guaranteed to exist. Therefore, we do not have to create any sort
of state prior to trying to force a read.
