RDMA/core: Clarify rdma_ah_find_type
[ Upstream commit a6532e7139660c103dda181aa5b2c734aa26ed6c ]
iWARP does not use rdma_ah_attr_type, and for this reason we do not have a
RDMA_AH_ATTR_TYPE_IWARP. rdma_ah_find_type should not even be called on iwarp
ports and for clarity it shouldn't have a special test for iWarp.
This changes the result from RDMA_AH_ATTR_TYPE_ROCE to RDMA_AH_ATTR_TYPE_IB
when wrongly called on an iWarp port.
Fixes: 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types")
