[libvirt] [PATCH 4/4] virsh: free the caps list properly if one of them is invalid



VIR_FREE(caps) is not enough to free an array allocated
by vshStringToArray.

==17== 4 bytes in 1 blocks are definitely lost in loss record 4 of 728
==17==    by 0x4EFFC44: virStrdup (virstring.c:554)
==17==    by 0x128B10: _vshStrdup (virsh.c:125)
==17==    by 0x129164: vshStringToArray (virsh.c:218)
==17==    by 0x157BB3: cmdNodeListDevices (virsh-nodedev.c:409)
