{IB, net}/mlx5: Move the modify QP operation table to mlx5_ib
When modifying a QP, the desired operation was determined in the mlx5_core using a transition table that takes the current state, the final state, and returns the desired operation. Since this logic will be used for Raw Packet QP, move the operation table to the mlx5_ib.
