ifuzz: fix 2-byte vex decoding
The intel documentation states, in section:
2.3.6 "Instruction Operand Encoding and VEX.vvvv, ModR/M"
The following:
"VEX.m-mmmm is only available on the 3-byte VEX. The 2-byte VEX implies
a leading 0Fh opcode byte."
This lead the decode function to reject the following as an unknown
instruction:
"c5 f9 6e c1 vmovd %ecx,%xmm0"
With this fix, it correctly decodes it as a 4 byte instruction.
