Silence REGION_INIT() warning.

Browse source 
Evaluating the address of a BoxRec as a boolean gives this warning:

  i830_driver.c:2317: warning: the address of 'ScreenBox' will always
  evaluate as 'true'

which is pretty annoying.  This patch compares the address to NULL to
avoid the pointer->bool conversion and gets rid of the warning.  Seems
like a lame hack, but the warning is worse.
