net/smc: Enable module load on netlink usage

Previously, the smc and smc_diag modules were automatically loaded as
dependencies of the ism module whenever an ISM device was present.
With the pending rework of the ISM API, the smc module will no longer
automatically be loaded in presence of an ISM device. Usage of an AF_SMC
socket will still trigger loading of the smc modules, but usage of a
netlink socket will not.
This is addressed by setting the correct module aliases.
