stage_tmpfile test gets current data_version

Browse Source 
The stage_tmpfile test util was written when fallocate didn't update
data_version for size extensions.  It is more correct to get the
data_version after fallocate changes data_versions for however many
transactions, extent allocations, and i_size extensions it took to
allocate space.
