selftests/sgx: Ensure enclave data available during debug print

In support of debugging the SGX tests print details from
the enclave and its memory mappings if any failure is encountered
during enclave loading.

When a failure is encountered no data is printed because the
printing of the data is preceded by cleanup of the data.

Move the data cleanup after the data print.
