Subject: [PATCH] qemu: Fix USB by product with security enabled

We need to call PrepareHostdevs to determine the USB device path before
any security calls. PrepareHostUSBDevices was also incorrectly skipping
all USB devices.

Subject: [PATCH] security: selinux: Fix crash when releasing non-existent label

This can be triggered by the qemuStartVMDaemon cleanup path if a
VM references a non-existent USB device (by product) in the XML.
