ltp/fsx: do size check after closeopen operation

I was running down a i_size problem and was missing the failure until
the next iteration of fsx operations because we do the file size check
_before_ the closeopen operation.  Move it after the closeopen operation
so we can catch problems where the file gets messed up on disk.
