ALSA: bebob: Fix a missing to unlock mutex in error handling case

Browse source 
In error handling case, special_clk_ctl_put() returns without unlock_mutex(),
therefore the mutex is still locked. This commit moves mutex_lock() after
the error handling case.

This commit is my solution for this post.
