f2fs: fix incorrect return value in f2fs_sanity_check_ckpt()

Browse Source 
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.

[1] https://lkml.org/lkml/2021/9/19/207

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.
