IB/rdmavt: Set QP allowed opcodes after QP allocation
Currently QP allowed_ops is set after the QP is completely initialized. This curtails the use of this optimization for any initialization before allowed_ops is set. Fix by adding a helper to determine the correct allowed_ops and moving the setting of the allowed_ops to just after QP allocation.
