smb: client: add tracepoints for deferred handle caching

Browse source

Add tracepoints to observe handle caching behavior.

smb3_open_cached: emitted when an open reuses a cached handle from
a previous deferred close, avoiding a network round-trip

smb3_close_cached: emitted when a close is deferred (handle cached
for potential reuse by subsequent opens)
