[ Upstream commit ca98d72141dd81f42893a9a43d7ededab3355fba ]
As Pavel Machek reported in [1]
This code looks quite confused: part of function returns 1 on corruption, part returns -errno. The problem is not stable-specific.

Let's fix to make 'insane cp_payload case' to return 1 rater than EFSCORRUPTED, so that return value can be kept consistent for all error cases, it can avoid confusion of code logic.
