jffs2: Fix corruption when flash erase/write failure
Erase errors such as: "Newly-erased block contained word 0xa4ef223e at offset 0x0296a014" and failure to write the clean marker, moves the offending erase block to erasing list before calling jffs2_erase_failed(). This is bad as jffs2_erase_failed() will also move the block to the bad_list, but is now moving the wrong block, causing FS corruption.
