helper/log: remove dead code in log_forward() 

Commit f1be0e6af2 ("HELPER/LOG:
review unused symbols") removed a set of unused functions and,
as consequence, there is no code anymore that sets the variable
"log_forward_count". But, the commit above did not removed the
code (now dead) that depends on "log_forward_count" set.

Remove the code dependant on "log_forward_count" set and the
variable itself.
