can: mcp251xfd: mcp251xfd_ring_set_ringparam(): assign missing tx_obj_num_coalesce_irq

[ Upstream commit 1613fff7a32e1d9e2ac09db73feba0e71a188445 ]

If the a new ring layout is set, the max coalesced frames for RX and
TX are re-calculated, too. Add the missing assignment of the newly
calculated TX max coalesced frames.
