qemuDomainAttachNetDevice: Don't construct network device properties under monitor lock

Browse Source 
After the 'qemuFDPass' code was refactored we no longer need to hand off
the FD to qemu before we know the path for it.

Thus the call to qemuBuildHostNetProps can be moved outside of the
monitor critical section.
