[PATCH openEuler-22.03-LTS-SP1] btrfs: clean up our handling of refs == 0 in snapshot delete

From: Josef Bacik <josef(a)toxicpanda.com> stable inclusion from stable-v5.10.226 commit c60676b81fab456b672796830f6d8057058f029c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9NE CVE: CVE-2024-46840 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b8ccef048354074a548f108e51d0557d6adfd3a3 ] In reada we BUG_ON(refs == 0), which could be unkind since we aren't holding a lock on the extent leaf and thus could get a transient incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code. Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert that to proper error handling. Also adjust the error message so we can actually do something with the information.
