Heinrich Schuchardt 081d515084 efi/libstub: Avoid returning uninitialized data from setup_graphics()
Currently, setup_graphics() ignores the return value of efi_setup_gop(). As
AllocatePool() does not zero out memory, the screen information table will
contain uninitialized data in this case.

We should free the screen information table if efi_setup_gop() returns an
error code.
