[PATCH 3/3] ASoC: bcm: cygnus: use scoped child node loop

[Cássio Gabriel]

cygnus_ssp_probe() manually puts the current child node before returning
from the child parsing loop on error.

Use for_each_available_child_of_node_scoped() so the current child node is
released automatically on early return and normal loop exit.
