Resolve Coverity issue regarding not checking return value

Coverity complains that the call to virPCIDeviceDetach() in
qemuPrepareHostdevPCIDevices() doesn't check status return like
other calls.  Seems this just was lurking until a recent change
to this module resulted in Coverity looking harder and finding
the issue.  Introduced by 'a4efb2e33' when function was called
'pciReAttachDevice()'

Just added a ignore_value() since it doesn't appear to matter
if the call fails since we're on a failure path already.
