net/netlink_compat: Fix a missing check of nla_parse_nested

[ Upstream commit 89dfd0083751d00d5d7ead36f6d8b045bf89c5e1 ]

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.
