Revert "ucounts: Increase ucounts reference counter before the security hook"
stable inclusion from stable-5.10.63 commit 0c1443874e1cb359b377a0e383c0dcce81aefa12 bugzilla: 182231 https://gitee.com/openeuler/kernel/issues/I4EFS1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0c1443874e1cb359b377a0e383c0dcce81aefa12 -------------------------------- This reverts commit b493af3a66e067f93e5e03465507866ddeabff9e which is commit bbb6d0f3 upstream. The "original" commit 905ae01c ("Add a reference to ucounts for each cred"), should not have been applied to the 5.10.y tree, so revert it, and the follow-on fixup patches as well.
