Subject: [PATCH] Fix decompile/deobfuscation error in BlockPosition iterator

Some of the fields in the anonymous class are named the same as the
surrounding method's parameters, which caused the fields to be
initialized incorrectly.

That way it keeps returning the same block position, resulting
in an infinite loop during chunk generation.
