ALSA: control: obsolete user_ctl_lock
At a previous commit, concurrent requests for TLV data are maintained exclusively between read requests and write/command requests. TLV callback handlers in each driver has no risk from concurrent access for reference/change. In current implementation, 'struct snd_card' has a mutex to control concurrent accesses to user-defined element sets. This commit obsoletes it.
