source4/torture: Drop unused variable tdif
clang complains:
../../source4/torture/basic/denytest.c:1805:11: error: variable 'tdif' set but not used [-Werror,-Wunused-but-set-variable]
int64_t tdif;
^
That is, the variable is initialised and updated but the value is
never used.
Perhaps it is meant to be used in the nearby torture_comment() call,
but it has been this was since commit
cb1cff90f165d82cbbf1dd87e475a1b13984d45e from 2004. Just drop it.
