net/smc: add pnet table namespace support
This patch adds namespace support to the pnet table code. Each network namespace gets its own pnet table. Infiniband and smcd device pnetids can only be modified in the initial namespace. In other namespaces they can still be used as if they were set by the underlying hardware.
