[PATCH v2] netfilter: conntrack: remote a return value of the 'seq_print_acct' function.

[Gavrilov Ilia]

The static 'seq_print_acct' function always returns 0.

Change the return value to 'void' and remove unnecessary checks.

Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

Fixes: 1ca9e41770cb ("netfilter: Remove uses of seq_<foo> return values")
