[libvirt] [PATCH 6/6] Use help string "-device driver, " when getting additional caps.

[Li Zhang]

From: Li Zhang <zhlcindy at linux.vnet.ibm.com>

QEMU of upstream and PPC64 can support "-device driver,?",
But the help string is "-device driver,help",

This patch is to replace "-device driver,?" with "-device driver,".
