Subject: IB/ipoib: Prevent setting negative values to max_nonsrq_conn_qp
Patch-mainline: v4.13-rc5
Git-commit: 11f74b40359b19f760964e71d04882a6caf530cc
References: bsc#1046307 FATE#322941
Don't allow negative values to max_nonsrq_conn_qp. There is no functional
impact on a negative value but it is logicically incorrect.
Fixes: 68e995a29572 ("IPoIB/cm: Add connected mode support for devices without SRQs")
