Yes, it's true that mthca doesn't support memory windows yet.

Looking at the code, I don't see anything obviously wrong. What is
the status field of the completions that you see with the opcode
IBV_WC_BIND_MW? If the status is not success, then the opcode field
is undefined (only the wrid is valid).
