tipc: fix link name length check
[ Upstream commitfd567ac20c
] In commit4f07b80c97
("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:4f07b80c97
