[PATCH V0.1 2/3] selftests: sev_migrate_tests: Fix sev_ioctl()

[Peter Gonda]

TEST_ASSERT in SEV ioctl was allowing errors because it checked return
value was good OR the FW error code was OK. This TEST_ASSERT should
require both (aka. AND) values are OK.

Currently issues with the PSP driver functions mean the firmware error
is not always reset to SEV_RET_SUCCESS when a call is successful.
Mainly sev_platform_init() doesn't correctly set the fw error if the
platform has already been initialized.
