WIP: Reorder IB kernel modules to fix module unloading

[jovial]

Before I was seeing kernel modules failing to be unloaded because we were trying to unload the dependent modules before the dependencies had been unloaded.

Looks like centos is loading extra modules:

[centos@test-openhpc-login-0 ~]$ lsmod | grep iw_cm
iw_cm                  43514  1 rdma_cm
ib_core               255469  13 rdma_cm,ib_cm,iw_cm,rpcrdma,mlx5_ib,ib_srp,ib_iser,ib_srpt,ib_umad,ib_uverbs,rdma_ucm,ib_ipoib,ib_isert

so, you still see:
