- Increase waiting time for DRQ removal inside AtapiInterrupt twice.

Browse source 
- Don't disable/enable IDE controller interrupts in AtapiSendCommand. This confuses Virtual Box's controller (it consumes one interrupt without ever emitting it) and thus sending any ATAPI command fails.
- Turn off ATAPI DMA raw read support by default. It seems to be incompatible with (at least) Virtual Box IDE controller.
See issue #3645 for more details.
