Søren Schmidt 8ea3ce2aac Refine the detach/attach code. 
Proberly fail outstanding bio requests on devices that are detached.

This makes it possible to change between disk/cdrom/dvd/whathaveyou
in a notebook, just by suspending it, changing the device in the
bay (or what you model calls it), unsuspend and the ATA driver
will figure out what disappeared and properly fail those, and attach
any new devices found.
