Subject: [PATCH 5.19 1128/1157] ext4: unindent codeblock in ext4_xattr_block_set()

From: Jan Kara <jack@...e.cz>

[ Upstream commit fd48e9acdf26d0cbd80051de07d4a735d05d29b2 ]

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.

CC: stable@...r.kernel.org
Fixes: 82939d7999df ("ext4: convert to mbcache2")
