Eduardo Otubo aa1530dec4 filter-mirror: segfault when specifying non existent device 
When using filter-mirror like the example below where the interface
'ndev0' does not exist on the host, QEMU crashes into segmentation
fault.

 $ qemu-system-x86_64 -S -machine pc -netdev user,id=ndev0 -object filter-mirror,id=test-object,netdev=ndev0

This happens because the function filter_mirror_setup() does not check
if the device actually exists and still keep on processing calling
qemu_chr_find(). This patch fixes this issue.
