Subject: [PATCH -next] interconnect: qcom: fix return value of qnoc_probe

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/interconnect/qcom/msm8916.c: In function 'qnoc_probe':
drivers/interconnect/qcom/msm8916.c:439:7: warning:
 variable 'ret' set but not used [-Wunused-but-set-variable]

if icc_node_create failed, err code 'ret' will be returned,
so it cannot be a local variable in for-loop.

Fixes: 8d9300299a40 ("interconnect: qcom: Add msm8916 interconnect provider driver")
