tcp: ulp: diag: always print the name if any

Browse source

Since its introduction in commit 61723b3932 ("tcp: ulp: add functions
to dump ulp-specific information"), the ULP diag info have been exported
only if the requester had CAP_NET_ADMIN.

At least the ULP name can be exported without CAP_NET_ADMIN. This will
already help identifying which layer is being used, e.g. which TCP
connections are in fact MPTCP subflow.
