[PATCH] mountd: group length not being set correctly in auth_unix_gid

[Steve Dickson <steved@redhat.com>]

From: Rinat Bikov <becase@altlinux.org>

Commit 9274e94d introduce dynamic buffering for gids lists.
In that patch there was a bug that only used the dynamic
length on the first call, resulting in the dynamic length
not being dynamic at all.
