Trivial fix to remove sparse warnings:

  drivers/staging/gasket/gasket_page_table.c:884:40: warning: Using plain integer as NULL pointer
  drivers/staging/gasket/gasket_page_table.c:1743:57: warning: Using plain integer as NULL pointer
  drivers/staging/gasket/gasket_page_table.c:1768:57: warning: Using plain integer as NULL pointer
