Buffer: Fix race condition in enrolled buffer access

Accessing enrolled buffers from multiple clients is only
protected by a spinlock, which is a potential risk.
We should add a lock to protect the buffer access process
on multiple LWIS clients because it could be modified by
other processes, such as the disenroll buffer and delete list processes.
