jffs2: Fix long-standing bug with symlink garbage collection.
Ever since jffs2_garbage_collect_metadata() was first half-written in February 2001, it's been broken on architectures where 'char' is signed. When garbage collecting a symlink with target length above 127, the payload length would end up negative, causing interesting and bad things to happen.
