Subject: [PATCH] virDomainHostdevDefFree: Don't leak privateData

https://bugzilla.redhat.com/show_bug.cgi?id=1357346

After 27726d8c21 a privateData is allocated in
virDomainHostdevDefAlloc(). However, the counter part - freeing
them in Free() is missing which leads to the following memory
leak:

==6489== 24 bytes in 1 blocks are definitely lost in loss record 684 of 1,003
==6489==    at 0x4C2C070: calloc (vg_replace_malloc.c:623)
==6489==    by 0x54B7C94: virAllocVar (viralloc.c:560)
==6489==    by 0x5517BE6: virObjectNew (virobject.c:193)
==6489==    by 0x1B400121: qemuDomainHostdevPrivateNew (qemu_domain.c:798)
==6489==    by 0x5557B24: virDomainHostdevDefAlloc (domain_conf.c:2152)

==6489==    by 0x5583B07: virDomainDefParse (domain_conf.c:17417)
==6489==    by 0x5583B95: virDomainDefParseFile (domain_conf.c:17441)
