Now, when we can pass list of pages between REE and TEE it is possible to use temporary memory references that are not located in a preallocated shared memory area. By employing OPTEE_MSG_ATTR_NONCONTIG parameter attribute, REE can provide own buffer as a temporary memory reference.
Actually, such parameters are indistinguishable from registered shared memory references. So, when OP-TEE spots temporary memory reference with OPTEE_MSG_ATTR_NONCONTIG attribute, it will create `mobj_reg_shm` for it. After call was handled, it will free that mobj.
