audio: pipewire: Remove redundant locks 

The io_list_check_add() and io_list_remove() functions are only ever called from within the Pipewire thread loop, so the locks are redundant.  io_list_sort() is called from within a lock in the device detection function, so those additional locks are redundant as well.
