hulk inclusion
category: bugfix
bugzilla: 186975, https://gitee.com/openeuler/kernel/issues/I5HT6F
CVE: NA

Reference: https://patchwork.ozlabs.org/project/linux-ext4/list/?series=309169

--------------------------------

Remove unnecessary else (and thus indentation level) from a code block
in ext4_xattr_block_set(). It will also make following code changes
easier. No functional changes.
