The only valid (embedded or explicit) prefix being the data size one (which is a fairly common pattern), avoid going through prefix_table[]. Instead extend the "required prefix" logic to also handle PREFIX_DATA alone in a table entry, now used to identify this case. This requires moving the (adjusted) ->prefix_requirement logic ahead of the printing of stray prefixes, as the latter needs to observe the new setting of PREFIX_DATA in used_prefixes. Also add PREFIX_OPCODE on related entries when previously there was mistakenly no decode step through prefix_table[].
