infiniband: avoid dereferencing uninitialized dst on error path
With commit eea40b8f624f ("infiniband: call ipv6 route lookup
via the stub interface"), if the route lookup fails due to
ipv6 being disabled, the dst variable is left untouched, and
the following dst_release() may access uninitialized memory.
Since ipv6_dst_lookup() always sets dst to NULL in case of
lookup failure with ipv6 enabled, fix the above just
returning the error code if the lookup fails.
Fixes: eea40b8f624 ("infiniband: call ipv6 route lookup via the stub interface")
