ntb: transport: Fix uninitialized mutex

When the mutex 'link_event_lock' was introduced, it was never
initialized and it triggers kernel warnings when used with locking
debug turned on. Add initialization for the mutex.

Fixes: 3db835dd8f9a ("ntb: Add mutex to make link_event_callback executed linearly.")
