Gaosheng Cui f380f895db firmware_loader: Fix possible resource leak in fw_log_firmware_info() ...

[ Upstream commit 369a9c046c ]

The alg instance should be released under the exception path, otherwise
there may be resource leak here.

To mitigate this, free the alg instance with crypto_free_shash when kmalloc
fails.
