smb: client: add tracepoint for local lock conflicts

Browse source

Add smb3_lock_conflict tracepoint that fires when a byte-range
lock request conflicts with an existing cached lock. This helps
debug lock contention issues when locks are cached locally due
to oplocks/leases.

The trace includes both the requested and conflicting lock details:
- Requested: offset, length, type
- Conflicting: offset, length, type, pid (lock holder)
