net/netlink_compat: Fix a missing check of nla_parse_nested
In tipc_nl_compat_sk_dump(), if nla_parse_nested() fails, it could return an error. To be consistent with other invocations of the function call, on error, the fix passes the return value upstream. Signed-off-by: Aditya Pakki <pakki001@umn.edu> Signed-off-by: David S. Miller <davem@davemloft.net>
