Eric Dumazet 5e7f3e0381 af_unix: fix lockdep positive in sk_diag_dump_icons() 
[ Upstream commit 4d322dce82a1d44f8c83f0f54f95dd1b8dcf46c9 ]

syzbot reported a lockdep splat [1].

Blamed commit hinted about the possible lockdep
violation, and code used unix_state_lock_nested()
in an attempt to silence lockdep.

It is not sufficient, because unix_state_lock_nested()
is already used from unix_state_double_lock().

We need to use a separate subclass.

This patch adds a distinct enumeration to make things
more explicit.

Also use swap() in unix_state_double_lock() as a clean up.

v2: add a missing inline keyword to unix_state_lock_nested()

[1]
