[PATCH 6/6] soc: qcom: smem: check sooner in qcom_smem_set_global_partition()

[Alex Elder]

There's no sense in scanning the partition table again if we know
the global partition has already been discovered.  Check for a
non-null global_partition pointer in qcom_smem_set_global_partition()
immediately.
