ntb: transport: Fix uninitialized mutex
[ Upstream commit 2ccb5e8dbcd2dedf13e0270165ac48bd79b7f673 ]
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.")
