[ofa-general] [PATCH] fix some ehca limits

[Anton Blanchard]

I had trouble getting DAPL to work on eHCA, this turned out to be a
negative value in max_cqe. max_pd and max_ah are currently negative too,
fix them up at the same time.

Before:

        max_cqe:                        -64
        max_pd:                         -1
        max_ah:                         -1

After:
        max_cqe:                        2147483647
        max_pd:                         2147483647
        max_ah:                         2147483647
