py/objint: Remove unreachable code checking for int type in format func.

All callers of mp_obj_int_formatted() are expected to pass in a valid int
object, and they do:

- mp_obj_int_print() should always pass through an int object because it is
  the print special method for int instances.

- mp_print_mp_int() checks that the argument is an int, and if not converts
  it to a small int.

This patch saves around 20-50 bytes of code space.
