Ilya Shipitsin 96cd04f8db CLEANUP: fix typo in naming for variable "unused" 
In resolvers.c:rslv_promex_next_ts() and in
stick-tables.c:stk_promex_next_ts(), an unused argument was mistakenly
called "unsued" instead of "unused". Let's fix this in a separate patch
so that it can be omitted from backports if this causes build problems.
