[RESEND PATCH] mfd: Add missing of_node_put for loop iteration

[Krzysztof Kozlowski]

Early exits from for_each_child_of_node() should decrement the
node reference counter.  Reported by Coccinelle:

  drivers/mfd/mfd-core.c:197:2-24: WARNING:
    Function "for_each_child_of_node" should have of_node_put() before goto around lines 209.

Fixes: c94bb233a9fe ("mfd: Make MFD core code Device Tree and IRQ domain aware")
