Use correct minio error (#26634) (#26639)

Backport #26634 by @delvh

Previously, `err` was defined above, checked for `err == nil` and used
nowhere else.
Hence, the result of `convertMinioErr` would always be `nil`.
This leads to a NPE further down the line.
That is not intentional, it should convert the error of the most recent
operation, not one of its predecessors.
