client/X11: Check arguments in xf_Bitmap_SetSurface

Arguments of xf_Bitmap_SetSurface are not checked before use currently
which may lead to segfaults. It may happen if bitmap is not found in a
cache from some reason. Let's check the arguments before use similarly
as it is done in client/Windows/wf_graphics.c in order to avoid segfaults.
