Remove unused lock server alloc and wri

While checking in on some other code I noticed that we have lingering
allocator and writer contexts over in the lock server.  The lock server
used to manage its own client state and recovery.  We've sinced moved
that into shared recov functionality in the server.  The lock server no
longer manipulates its own btrees and doesn't need these unused
references to the server's contexts.
