branches/zip: UT_LIST_VALIDATE(): Assert that the link is non-NULL

Browse source 
before dereferencing it.  In this way, ut_list_node_313 will be
pointing to the last non-NULL list item at the time of the assertion
failure.  (gcc-4.3.2 -O3 seems to optimize the common subexpressions
and make the variable NULL, though.)
