Lars-Peter Clausen 34e81ab455 ASoC: Fix component lists locking
Any access to the component_list, codec_list and platform_list needs to be
properly locked by the client_mutex. Otherwise undefined behavior can occur
if the list is modified in one thread and concurrently accessed from another
thread.

This patch adds the missing locking to the debugfs file handlers that
display the registered components, as well as the various components
unregister functions.

Furthermore the client_lock is now held for the whole
snd_soc_instantiate_card() sequence to make sure that component removal does
not race against the card registration.
