[PATCH] regulator: Avoid a double 'of_node_get' in 'regulator_of_get_init_node()'

[Christophe JAILLET]

'for_each_available_child_of_node()' already performs an 'of_node_get()'
on child, so there is no need to perform another one before returning.
Otherwise, a double 'get' is performed and a resource may never be
released.

Fixes: 925c85e21ed8 ("regulator: Factor out location of init data OF node")
