    if_ti: Fix -Waddress warnings from GCC 12.5
    
    The 'ti_event_ring' and 'ti_tx_ring' are embedded arrays in
    'struct ti_ring_data', so the checks were meaningless.  In addition, the
    'sc->ti_rdata' area is initialized in ti_attach(); it's always not
    NULL after a successful attach.  So just remove the checks to fix the
    following warnings from GCC 12.5:
    
    ```
    /usr/src/sys/dev/netif/ti/if_ti.c: In function 'ti_handle_events':
    /usr/src/sys/dev/netif/ti/if_ti.c:508:41: warning: the comparison will always evaluate as 'false' for the address of 'ti_event_ring' will never be NULL [-Waddress]
      508 |         if (sc->ti_rdata->ti_event_ring == NULL)
          |                                         ^~
    In file included from /usr/src/sys/dev/netif/ti/if_ti.c:116:

          |                                 ^~~~~~~~~~~~~

          |                                      ^~

     1077 |         struct ti_tx_desc       ti_tx_ring[TI_TX_RING_CNT];
          |                                 ^~~~~~~~~~
    ```
    
    By the way, FreeBSD overhauled the DMA/ring code (see commit
    b7c2632d6af08a5dc053adc201f997667815e0ee), so a better fix would be sync
    the driver with FreeBSD.
