UBI: rename struct ubi_scan_info
Rename 'struct ubi_scan_info' to 'struct ubi_attach_info'. This is part of the code re-structuring I am trying to do in order to add fastmap in a more logical way. Fastmap can share a lot with scanning, including the attach-time data structures, which all now have "scan" word in the name. Let's get rid of this word.
