IB/addr: Pass network namespace as a parameter
Add network namespace support to the ib_addr module. For that, all the address resolution and matching should be done using the appropriate namespace instead of init_net. This is achieved by: 1. Adding an explicit network namespace argument to exported function that require a namespace. 2. Saving the namespace in the rdma_addr_client structure. 3. Using it when calling networking functions. In order to preserve the behavior of calling modules, &init_net is passed as the parameter in calls from other modules. This is modified as namespace support is added on more levels.
