Log:
MFP4(128855, 129015):
- Trying to eliminate another racing by replacing the timeout(9) with
callout APIs. In addition to that, the callout_drain() in an_detach()
help us to avoid a possible panic-on-free due to the callout API tries
to lock a destroyed mutex.
- In an_stats_update(), check the return value of an_read_record(). This
should reduce the chance of device removal(PCCARD) panic [2].
- Adding a comment to state the fact that an_stats_update() is now called
via callout(9) with a lock held [2].
