virtio-serial: avoid crash when port has no name
It seems "name" is not mandatory, and the following command line (based
on one generated by current libvirt) will crash qemu at start:
qemu-system-x86_64 \
-device virtio-serial-pci \
-device virtserialport,name=foo \
-device virtconsole
Program received signal SIGSEGV, Segmentation fault.
__strcmp_ssse3 () at ../sysdeps/x86_64/strcmp.S:210
210 movlpd (%rsi), %xmm2
Missing separate debuginfos, use: debuginfo-install
