net: 3c509: make the array if_names static const, makes object smaller

Don't populate the array if_names on the stack but instead it
static const. Makes the object code smaller by 99 bytes.

Before:
   text    data     bss     dec     hex filename
  27886   10752     672   39310    998e ./drivers/net/ethernet/3com/3c509.o

After:
   text    data     bss     dec     hex filename
  27723   10816     672   39211    992b ./drivers/net/ethernet/3com/3c509.o
