librbd: pass an uint64_t to clip_io() as the 3rd param

Browse Source 
because, on arm32, size_t is "unsigned", while uint64_t is "long long
unsigned int", compiler is not able to promote the former to the latter
automatically. and ImageRequest::Extents::value_type::second_type is
indeed uint64_t, which is expected by clip_io(). so let's just use
"auto" here.
