Sinan Kaya 97d82a48d7 IB/mlx4: Eliminate duplicate barriers on weakly-ordered archs 
Code includes wmb() followed by writel(). writel() already has a barrier on
some architectures like arm64.

This ends up CPU observing two barriers back to back before executing the
register write.

Since code already has an explicit barrier call, changing writel() to
writel_relaxed().
