Subject: qemu_driver.c: don't unlink(NULL) on OOM error path
X-Git-Tag: v0.7.5~75

qemu_driver.c: don't unlink(NULL) on OOM error path

* src/qemu/qemu_driver.c (qemudDomainMigratePrepareTunnel): Upon an
out of memory error, we would end up with unixfile==NULL and attempt
to unlink(NULL).  Skip the unlink when it's NULL.
