Eric Dumazet cb022b8b01 macvlan: annotate data-races around port->bc_queue_len_used 
[ Upstream commit 1ef5789d99 ]

port->bc_queue_len_used is read and written locklessly,
add READ_ONCE()/WRITE_ONCE() annotations.

While WRITE_ONCE() in macvlan_fill_info() is not yet needed,
it is a prereq for future RTNL avoidance.

Fixes: d4bff72c84 ("macvlan: Support for high multicast packet rate")
