I actually think this is a spec bug:
IB spec requires the following transitions in modify qp:
        Any State to Error
	Any state to Reset

If we are in reset state, both of these do not make any sense.

To Error from reset is especially hard to implement, and I think
this will actually create bugs in application (if it did "to error" I
think its expecting completions with error).

I'll try speaking with our representatives at the IBTA to remove this requirement.
