Wei Wang 97a1e65df7 psp: use unrcu_pointer() for the cmpxchg() on netdev psp_dev 
sparse reports:

  net/psp/psp_nl.c:513:13: sparse: sparse: cast removes address space
  '__rcu' of expression

cmpxchg() returns typeof(*ptr) and its internal casts strip the __rcu
annotation. Wrap it in unrcu_pointer(), the documented way to use an
__rcu pointer with xchg() and friends.

This was introduced by commit 06c2dce2d0 ("psp: add new netlink cmd
for dev-assoc and dev-disassoc").

No functional change intended.
