[PATCH] Fix second check for n_tries in forward.cc to use value of forward_max_tries too

[Silamael]

Hi!

There are two checks against n_tries in forward.cc but only at one place
the configured value of forward_max_tries is used for the check.
This patch fixes the second check to use also the configured value
instead of the value of 10.
