SEGV backtrace

Weston segfaults (see attached backtrace) when using the tablet-shell.so and resuming from a LOCKED state.  This may be related to bug 57634.

1. Load Weston with tablet-shell.so (see bug 57636)
2. Wait for tablet-shell to emit "switching to state LOCKED (from STARTING)"
3. Move mouse to trigger an unlock and notice the segfault.

    tablet-shell: Fix copy and paste error in unlock handler
    
    The signal handler was using the wrong member to find the containing
    structure of the unlock listener.
