bonding/bond_alb.c: Apply rcu_access_pointer() to avoid sparse false positive
The sparse checking for rcu_assign_pointer() was recently upgraded
to reject non-__kernel address spaces. This also rejects __rcu,
which is almost always the right thing to do. However, the use in
bond_alb_handle_active_change() is legitimate: It is assigning a pointer
to an element from an RCU-protected list, and all elements of this list
are already visible to caller.
This commit therefore silences this false positive by laundering the
pointer using rcu_access_pointer() as suggested by Josh Triplett.
