RDMA/rxe: Bump up default maximum values used via uverbs

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.
