dma-heap: qcom: Relax checks in qti_smmu_proxy_register_callbacks()

Browse Source 
Users of qti_smmu_proxy_register_callbacks() need to be able to pass
in a NULL function pointer in order to change the behavior of the
mapping and unmapping callbacks in our SG operations. Remove the NULL
pointer check in qti_smmu_proxy_register_callbacks().
