Fix two bugs in DTrace tracing of accesscache and attrcache load events:
- Trace non-error loads into the access cache once, not zero times or
twice.
- Sometimes attr cache loads fail due to a race, in which case they are
aborted leading to an invalidation; in this case, trace only the flush,
not a load.
