x86/Intel: drop pointless suffix setting for "fword ptr"

No floating point insn accepts an "fword ptr" operand, so the "fword"
operand flag checking done by match_mem_size() is already sufficient;
the setting of the suffix has become meaningless anyway with
dc2be329b9 ("i386: Only check suffix in instruction mnemonic").
