qemu_monitor_text: Catch IOMMU/VFIO related errors in qemuMonitorTextAddDrive

Browse Source 
Because this is a HMP we're dealing with, there is nothing like
class of reply message, so we have to do some string comparison
to guess if the command fails. Well, with NVMe disks whole new
class of errors comes to play because qemu needs to initialize
IOMMU and VFIO for them. You can see all the messages it may
produce in qemu_vfio_init_pci().
