The error is only returned when kmalloc() fails.
Therefore, to return the error to the caller directly here, I changed the code.

   "fix error processing in btrfs_set_acl()"

what bug does it 'fix' ? IMHO this is a minor cleanup that is not much

pattern in the same if (acl) { ... } block, visually this does not help
the original code is correct and "looks ok".
