IB: Add rdma_cap_ib_switch helper and use where appropriate
Persuant to Liran's comments on node_type on linux-rdma mailing list: In an effort to reform the RDMA core and ULPs to minimize use of node_type in struct ib_device, an additional bit is added to struct ib_device for is_switch (IB switch). This is needed to be initialized by any IB switch device driver. This is a NEW requirement on such device drivers which are all "out of tree". In addition, an ib_switch helper was added to ib_verbs.h based on the is_switch device bit rather than node_type (although those should be consistent). The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs) as well as (IPoIB and SRP) ULPs are updated where appropriate to use this new helper. In some cases, the helper is now used under the covers of using rdma_[start end]_port rather than the open coding previously used.
