These printfs aren't really debug messages, but clearly indicate a bug if theyever become effective. Noone uses DEBUG_IDE, let's re-enable the checkunconditionally and make it an assertion instead of printfs in the device...

ide: Avoid canceling IDE DMA
The reason for not actually canceling the I/O is because withvirtualization and lots of VM running, a guest fs may mistake aoverload of the host, as an IDE timeout. So rather than canceling theI/O, it's safer to wait I/O completion and simulate that the I/O has...
