can: mcp251xfd: ring: update FIFO setup debug info

The recent change of the order of the TX and RX FIFOs is not reflected
in the debug info of the FIFO setup. This patch adjust the order and
additionally prints the base address of each FIFO.

Since the mcp251xfd_ring_init() may fail due to wrongly configured
FIFOs, printing of the FIFO setup is moved there. In case of an error
it would not be printed in mcp251xfd_ring_init().
