Why not ktls_*.c => tls_*.c ? 

Since we now have one TLS implementation, it would've been easier to maybe
repurpose TLS to be KTLS only and avoid renaming every TLS to KTLS in all
functions and files.

So just keep tls.c and all mlx5_tls_xyz functions and implement ktls
directly in them, the renaming will be done only on the ktls implementation
part of the code rather than in every caller.
