Vladimir Zapolskiy dbbd550d7c interconnect: qcom: sm8450: Fix NULL pointer dereference in icc_link_nodes() 
The change to dynamic IDs for SM8450 platform interconnects left two links
unconverted, fix it to avoid the NULL pointer dereference in runtime,
when a pointer to a destination interconnect is not valid:

    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008
    <...>
    Call trace:
