[issue2092] Panic: Bad link elm 0x... next->prev != elm

[Magliano Andrea (via DragonFly issue tracker)]

Nope, still same problem after 6 days... (sic)
Anyway, if the changes make sense, i would be glad if the are committed :)

What really disturbing is the log entry: 'ahci0.1: disk_rw: unknown state 6'
immediately before 'bad link elm'.
I changed the 'kprintf' at that point in code with 'panic' in the hope to get a
meaningful backtrace and eventually a core dump.

Thanks for your attention, Alex!
