[PATCH 1/3] ASoC: component: Propagate result of suspend and resume callbacks

[Cezary Rojewski <cezary.rojewski@xxxxxxxxx>]

From: Amadeusz Sławiński <amadeuszx.slawinski@xxxxxxxxxxxxxxx>

Both component->driver->suspend and ->resume() do return an int value
but it isn't propagated to the core later on. Update
snd_soc_component_suspend() and snd_soc_component_resume() so that the
possible errors are not squelched.
