Bug#653305: partman-auto: Please provide hook when disk is too small for the expert recipe

[Petter Reinholdtsen <pere@hungry.com>]

I discovered a typo in my patch.  $min_size should have been
$(min_size), and this lead me to discover that the min_size() function
would calculate the size every time it is called.  To avoid wasting
that time, I store the value in a variable at least for the duration
of the if block.  Here is an updated patch.
