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

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

[Steve Dickson]

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.

Looks good. It's almost the same, as I sent before "mountd: Fix
missing varialble assignment in auth_unix_gid"
(https://patchwork.kernel.org/patch/841452/) but it haven't got any
comments yet.

yeah.. Rinat sent me some private mail about this regression and
I made this posting before I remember you had already post a 
similar patch... So I did commit your patch...
