Rename the unique variable assigned as 'pit' which better
represents what it holds, to fix a warning reported by the
Clang static code analyzer:

    CC      hw/isa/i82378.o
  hw/isa/i82378.c:108:5: warning: Value stored to 'isa' is never read
      isa = isa_create_simple(isabus, "i82374");
      ^     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
