tracing: Remove unused variable 'dups' 

Reported by Clang [-Wunused-but-set-variable]

'commit c193707dde ("tracing: Remove code which merges duplicates")'
This commit removed the code which merges duplicates in detect_dups(),
but forgot to delete the variable 'dups' which used to merge
duplicates in the loop.

Now only 'total_dups' is needed, remove 'dups' for clean code.
