[PATCH 1/5] platform/x86/intel/ifs: Call release_firmware() when handling errors.

[Ashok Raj]

From: Jithu Joseph <jithu.joseph@xxxxxxxxx>

Missing release_firmware() due to error handling blocked any future image
loading.

Fix the return code and release_fiwmare() to release the bad image.

Fixes: 25a76dbb36dd ("platform/x86/intel/ifs: Validate image size")
