qemu: process: Don't leak priv->usbaddrs after VM restart

Browse Source 
Since the private data structure is not freed upon stopping a VM, the
usbaddrs pointer would be leaked:

==15388== 136 (16 direct, 120 indirect) bytes in 1 blocks are definitely lost in loss record 893 of 1,019
==15388==    at 0x4C2CF55: calloc (vg_replace_malloc.c:711)
