interconnect: exynos: fix node leak in probe PM QoS error path
commit 3aab264875bf3c915ea2517fae1eec213e0b4987 upstream.
Make sure to add the newly allocated interconnect node to the provider
before adding the PM QoS request so that the node is freed on errors.
Fixes: 2f95b9d5cf0b ("interconnect: Add generic interconnect driver for Exynos SoCs")
