Philippe Mathieu-Daudé d58d9f55a7 target/i386/sev: Mark unreachable code with g_assert_not_reached()
The unique sev_encrypt_flash() invocation (in pc_system_flash_map)
is protected by the "if (sev_enabled())" check, so is not
reacheable.
Replace the abort() call in sev_es_save_reset_vector() by
g_assert_not_reached() which meaning is clearer.
