[PATCH 4/8] interconnect: qcom: icc-rpm: skip duplicate SMD RPM node votes

[Dmitry Baryshkov]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

icc_sync_state() can invoke the provider set callback with the same
node as both source and destination. Do not submit a second RPM
bandwidth vote for that node.

Fixes: 751f4d14cdb4 ("interconnect: icc-rpm: Set destination bandwidth as well as source bandwidth")
