Bug 25440: Extra duplicated call to CGI->param method removed

Bug 25440: Extra duplicated call to CGI->param method removed

In code CGI param 'no_auto_renewal_after_hard_limit' assigned to
"$no_auto_renewal_after_hard_limit" var, and then just in the next line
again variable "$no_auto_renewal_after_hard_limit" reassigned with
call to same "$input->param('no_auto_renewal_after_hard_limit')".

Fixed. No logic or results should be changed.
