[PATCH] [netfilter-next] netfilter: remove unused refcount variable

[Arnd Bergmann]

The refcount variable was accidentally introduced without any reference
to it. Removing it again avoids this warning:

net/netfilter/nfnetlink_acct.c: In function 'nfnl_acct_try_del':
net/netfilter/nfnetlink_acct.c:329:15: error: unused variable 'refcount' 
[-Werror=unused-variable]

Fixes: b54ab92b84b6 ("netfilter: refcounter conversions")
