The next commit to the ATA driver will take care off this, either
by the user doing 'atacontrol detach dev' or by the timeout code
discovering that a divice went missing and proberly fail all the
outstanding bio requests..

This all needed the patch to subr_disk.c that I made earlier today,
but now we can actually do it, however some of the cleanup action
should be done by the higher levels and not by the device driver...
