target-s390x: fix exception for invalid operation code
When an operation code is not recognized (ie invalid instruction) an
operation exception should be generated instead of a specification
exception. The latter is for valid opcode, with invalid operands or
modifiers.
This give a very basic GDB support in the guest, as it uses the invalid
opcode 0x0001 to generate a trap.
