[PATCH] scsi: lpfc: fix potential memory leak in lpfc_read_object()

[Abdun Nihaal]

The memory allocated for sge_array inside lpfc_sli4_config() which is
attached to mbox, is not freed in one of the error path in
lpfc_read_object(). Fix that by calling lpfc_sli4_mbox_cmd_free()
instead of directly freeing the mbox.
