asiliantfb: add missing return statement

Commit 032220ba (asiliantfb: fix cmap memory leaks) changed the function
init_asiliant from void to int, resulting in the following compile warning:

  drivers/video/asiliantfb.c: In function `init_asiliant':
  drivers/video/asiliantfb.c:536: warning: control reaches end of non-void function

Fix the warning by returning 0.
