tipc: fix link name length check
[ Upstream commit fd567ac20cb0377ff466d3337e6e9ac5d0cb15e4 ]
In commit 4f07b80c9733 ("tipc: check msg->req data len in
tipc_nl_compat_bearer_disable") the same patch code was copied into
routines: tipc_nl_compat_bearer_disable(),
tipc_nl_compat_link_stat_dump() and tipc_nl_compat_link_reset_stats().
The two link routine occurrences should have been modified to check
the maximum link name length and not bearer name length.
Fixes: 4f07b80c9733 ("tipc: check msg->reg data len in tipc_nl_compat_bearer_disable")
