staging: kpc2000: added designated initializers to two structs.

Fixed the following two sparse warnings by using designated
initializers:

  drivers/staging/kpc2000/kpc2000/cell_probe.c:101:34: warning: Using plain integer as NULL pointer
  drivers/staging/kpc2000/kpc2000/cell_probe.c:364:34: warning: Using plain integer as NULL pointer
