Merge branch 'tcp-ulp-diag-expose-more-to-non-net-admin-users'

====================
tcp: ulp: diag: expose more to non net admin users

Since its introduction in commit 61723b393292 ("tcp: ulp: add functions
to dump ulp-specific information"), the ULP diag info have been exported
only to users with CAP_NET_ADMIN capability.

Not everything is sensitive, and some info can be exported to all users
in order to ease the debugging from the userspace side without requiring
additional capabilities.

First, the ULP name can be easily exported. Then more depending on each
layer:

 - On kTLS side, it looks like everything can be exported to all users:
   version, cipher type, tx/rx user config type, plus some flags.

 - On MPTCP side, everything but the sequence numbers are exported to
   all non net admin users, similar to TCP.
