hvm, ioemu: Fix the ide/cdrom emulation error on FC7 guest.
The new libata-eh in the Linux kernel is throwing a fit over the QEMU
cdrom device for two reasons:
1) DRQ can be set with ERR_STAT set. This is a violation of the ATAPI
state machine.
2) After a TEST_UNIT_READY ATAPI command is sent ERR_STAT is getting
set
which is correct. But, when the OS issues another ATAPI command
ERR_STAT is still set. Which is bad since the next expected command
from the OS is REQUEST_SENSE to find out why ERR_STAT is set.
