power: sequencing: pcie-m2: Fix device node reference leak in probe

In pwrseq_pcie_m2_probe(), ctx->of_node acquires an explicit reference
to the device node using of_node_get(), but there is no corresponding
of_node_put() in the driver's error handling paths or removal.

Since the ctx is tied to the lifecycle of the platform device, there
is no need to hold an additional reference to the device's own of_node.
