Re: [libvirt] [PATCH] conf: Fix libvirtd crash and memory leak caused by virDomainVcpuPinDel()

The function virDomainVcpuPinDel() used vcpupin_list to stand for def->cputune.vcpupin, which made the codes more readable. However, in this function, it will realloc vcpupin_list later. As the definition of realloc(), it may free vcpupin_list and then points it to a new-realloced address, but def->cputune.vcpupin doesn't point to the new address(it's freed however).

This patch uses def->cputune.vcpupin instead of vcpupin_list to do the realloc() job, to avoid invalid read or memory leaking.
