Thomas Huth bb38df846d hw/i386/vmmouse: Fix crash when using the vmmouse on a machine without vmport 
QEMU currently crashes when the user tries to use the "vmmouse" on a
machine without vmport, e.g.:

 $ x86_64-softmmu/qemu-system-x86_64 -machine microvm -device vmmouse
 Segmentation fault (core dumped)

or:

 $ x86_64-softmmu/qemu-system-x86_64 -device vmmouse -M pc,vmport=off
 Segmentation fault (core dumped)

Let's avoid the crash by checking for the vmport device first.
