video: s3c-fb: fix virtual resolution checking
This patch fixes mishandling in virtual resolution checking. Previously, virtual resolution is changed to virtual_x and virtual_y which mean the size for buffer allocation, when s3c_fb_check_var is called by fb_check_var. However, it is meaningless, since virtual_x and virtual_y are fixed and user cannot change virtual resolution. Therefore, virtual resolution should be more than resolution such as xres and yres.
