Subject: [PATCH 5.17 0218/1126] selftests/sgx: Ensure enclave data available during debug print

From: Reinette Chatre <reinette.chatre@...el.com>

[ Upstream commit 2db703fc3b15e7ef68c82eca613a3c00d43d70af ]

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.
