Jason Gunthorpe 19d6214ad6 IB/mlx5: Call io_stop_wc() after writing to WC MMIO 
This new function is defined only on ARM and serves to guarantee a barrier
in the WC operation. The barrier means that another run of this loop will
not combine with the stores this loop created.

On x86 this is happening implicitly because of the spin_unlock().
