--------------------------------

[ Upstream commit 5f0e4aede01cb01fa633171f0533affd25328c3a ]

In the for statement of lbs_allocate_cmd_buffer(), if the allocation of
cmdarray[i].cmdbuf fails, both cmdarray and cmdarray[i].cmdbuf needs to
be freed. Otherwise, there will be memleaks in lbs_allocate_cmd_buffer().
