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.
