Subject: rdma_find_network_type(): return MV2_NETWORK_CLASS_UNKNOWN when dev_list is freed
Patch-mainline: Not yet
Git-commit: 53c0c41fbd3728afb32cce7f23f596877e270911
References:

This makes rdma_open_hca() bail early, so it doesn't reach the
code which tries to free dev_list and avoids a double free.
