hpsa: avoid unneccesary calls to resource freeing functions
If hpsa_allocate_cmd_pool failed, we were calling two functions unnecessarily: hpsa_free_sg_chain_blocks(h); hpsa_free_cmd_pool(h); This didn't cause any problem, as those functions can tolerate being called when what they free hasn't been allocated (relevant pointers would be NULL) but it is potentially confusing.
