[infiniband] Add last_opened_ibdev(), analogous to last_opened_netdev()

Browse Source 
The minimal-surprise behaviour, when no explicit SRP initiator device
is specified, will probably be to use the most recently opened
Infiniband device.  This matches our behaviour with using the most
recently opened net device for PXE, iSCSI, AoE, NBI, etc.
