msm: smp2p: Fix init ordering problem

Client init sequence is dependent on core initialization and the
correct dependent order is done in Makefile. The smp2p functionality can
break if the dependent order is not maintained in Makefiles.

Remove Makefile link ordering dependence by adding -EPROBE_DEFER in case
client init called before core initialization.
