ip: Fix a data-race around sysctl_fwmark_reflect.

[ Upstream commit 51aa222506e1cbfb80864d8e5955953bfac6e4be ]

While reading sysctl_fwmark_reflect, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader.

Fixes: b2d88dea8bd2 ("net: add a sysctl to reflect the fwmark on replies")
