Gaosheng Cui 789a72498d 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.

Fixes: 02fe26f253 ("firmware_loader: Add debug message with checksum for FW file")
