[libvirt] [PATCH v2 2/2] esx: Fix SetAutoStart invalid pointer free

[Marcos Paulo de Souza]

esxVI_AutoStartPowerInfo_Free, which is called from
esxVI_HostAutoStartManagerConfig_Free, will always call VIR_FREE to free
memory from {start,stop}Action, leading to a invalid pointer.

With this patch applied, ESX can set autostart successfully to all it's
domains.

 Changes from v1:
 * Stop calling VIR_ALLOC_N and strcpy, and use VIR_STRNDUP instead
