[PATCH 3.2 018/199] IB/mlx4: Put non zero value in max_ah device attribute

[Ben Hutchings]

3.2.87-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Maor Gottlieb <maorg@xxxxxxxxxxxx>

commit 731e0415b4af3a133d0316e4dc8ef0ea57dc3fdf upstream.

Use INT_MAX since this is the max value the attribute can hold, though
hardware capability is unlimited.
