UBIFS: simplify LEB recovery function further
Further simplify 'ubifs_recover_leb()' by noticing that we have to call 'clean_buf()' in any case, and it is fine to call it if the offset is aligned to 'c->min_io_size'. Thus, we do not have to call it separately from every "if" - just call it once at the end. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
