i915: snprintf returns large values
i915: snprintf returns large values

snprintf() returns the number of bytes which would have been used if
there was enough space.  It can be larger than the size of the buffer.
Obviously in this case the buffer is large enough but everyone just
copy and pastes this code so it's better to limit it and set a good
example.
