net: Fix a data-race around sysctl_tstamp_allow_data.

[ Upstream commit f1b3c0f7b55afb05fa525f7015efb590add4c48d ]

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

Fixes: bf3cd3516bdd ("net-timestamp: no-payload only sysctl")
