Subject: [PATCH] evas_engines_gl_drm : Remove build warning

   - Remove unused variable.
   - Some variables were type casted into void* for arithmetic warning.
   - Changed type of 'last' variable type in _evas_outbuf_cb_pageflip() function.
     Because, That is only used as 'struct gbm_bo' type.
