Xiu Jianfeng 70e7f308d7 x86/xen: Fix memory leak in xen_init_lock_cpu() ...

[ Upstream commit ca84ce153d887b1dc8b118029976cc9faf2a9b40 ]

In xen_init_lock_cpu(), the @name has allocated new string by kasprintf(),
if bind_ipi_to_irqhandler() fails, it should be freed, otherwise may lead
to a memory leak issue, fix it.
