netlink_sock_diag: add const qualifiers

Add const qualifiers to auto variables and function arguments.
This change does not affect the code generated by the compiler,
the purpose of these "const" qualifiers is to highlight the intent.

* netlink_sock_diag.c (decode_unix_diag_vfs, decode_unix_diag_inode,
decode_unix_diag_rqlen): Add const qualifier to tcp, addr, and len
arguments.
