net: Fix data-races around netdev_max_backlog.
[ Upstream commit 5dcd08cd19912892586c6082d56718333e2d19db ]
While reading netdev_max_backlog, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers.
While at it, we remove the unnecessary spaces in the doc.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
