efi_loader: efi_current_var after SetVirtualAddressMap
Variable efi_current_var is a pointer to a physical memory address that becomes invalid after SetVirtualAddressMap(). Instead of converting it via ConvertPointer() simply set it to NULL. Fixes: b02a707152dc ("efi_loader: enable UEFI variables at runtime") Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
