Properly display extra data/address size prefixes

X86 disassembler checks data and address size prefixes when displaying
instruction mnemonic and operands.  For the extra data and address size
prefixes, their names depend only on the address mode, not the data and
address size prefixes.  This patch changes x86 disassembler not to check
the data and address size prefix when printing extra data and address size
prefixes.
