[PATCH 3/7] firmware: imx: ele: Bypass memcpy when ele_get_info() fails

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

When ele_get_info() fails, no sense to copy get_info_data to destination,
because get_info_data may contains garbage data, so bypass the copy.

Fixes: 106ffe5d78ad8 ("firmware: imx: add driver for NXP EdgeLock Enclave")
