soc/tegra: flowctrl: Release OF node reference on error

Browse Source 
tegra_flowctrl_init() obtains a reference from
of_find_matching_node() and currently releases it only after
of_address_to_resource() succeeds.

Release the reference before checking the resource conversion result so
the error path is balanced as well.
