From: Arvind Sankar <nivedita@alum.mit.edu>
If we've found a usable instance of the Graphics Output Protocol (GOP) with a framebuffer, it is possible that one of the later EFI calls fails while checking if any support console output. In this case status may be an EFI error code even though we found a usable GOP.
Fix this by explicitly return EFI_SUCCESS if a usable GOP has been located.
