maybe add return value for mca_pml_ucx_set_recv_status(), instead of extra branch in lines 615-616?

branch on 615-616 needed to call mca_pml_ucx_set_recv_status. I can move it in to mca_pml_ucx_set_recv_status_safe

maybe avoid setting temp mpi_status field if not needed
if (mpi_status != MPI_STATUS_IGNORE) {
return mca_pml_ucx_set_recv_status(mpi_status, ucp_status, info)
} else if (status == UCS_OK || status == CANCELED) {
return UCS_OK;

reutrn ERR_TRUNCATE

return ERR_INTERN

do we need this also in other places mca_pml_ucx_set_recv_status_safe is used?

fixed for MPI_Mrecv call, other locations are non-blocking MPI calls - not relevant
