tests/ide-test: Create a single unit-test covering more PRDT cases
Fuzzing the Linux kernel with syzkaller allowed to find how to crash qemu
using a special SCSI_IOCTL_SEND_COMMAND. It hits the assertion in
ide_dma_cb() introduced in the commit a718978ed58a in July 2015.
Currently this bug is not reproduced by the unit tests.
Let's improve the ide-test to cover more PRDT cases including one
that causes this particular qemu crash.
The test is developed according to the Programming Interface for
Bus Master IDE Controller (Revision 1.0 5/16/94).
