bcachefs: Bucket invalidate path improvements
- invalidate_one_bucket() now returns 1 when we don't have any buckets
on this device to invalidate, ensuring we don't spin
- the tracepoint invocation is moved to after the transaction commit,
and we now include the number of cached sectors in the tracepoint
