Subject: RDMA/ipoib: Fix check for return code from ib_create_srq
Patch-mainline: v4.19-rc1
Git-commit: e586e1e1b73f3dc020b82e6fc42c7789b7d0e95d
References: bsc#1103992 FATE#326009

Make sure to check for "-EOPNOTSUPP" instead of "-ENOSYS" which is the
return code from ib_create_srq() in case that it not supported.
