[PATCH v2 1/1] RDMA/rxe: Bump up default maximum values used via uverbs

[Rao Shoaib <Rao.Shoaib@oracle.com>]

From: Rao Shoaib <rshoaib@ca-dev141.us.oracle.com>

In our internal testing we have found that the
current maximum are too smalls. Ideally there should
be no limits but currently maximum values are reported
via ibv_query_device, so we have to keep maximum values
but they have been made suffiently large.

Resubmitting after fixing an issue reported by test robot.

Reported-by: kernel test robot <lkp@intel.com>
