Subject: [PATCH 3.16 037/370] IB/mlx5: Put non zero value in max_ah

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

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

From: Maor Gottlieb <maorg@...lanox.com>

commit 86695a6582e3b1c4895de2bde4e1022b3a8fbda0 upstream.

We put INT_MAX since this is the max value that can be held.
Though there is no hardware limitation, this is practically
a large enough number so we can use it.
