[PATCH v2 5/7] virCommandSetSendBuffer: Take double pointer of @buffer

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

The virCommandSetSendBuffer() function consumes passed @buffer,
but takes it only as plain pointer. Switch to a double pointer to
make this obvious. This allows us then to drop all
g_steal_pointer() in callers.
