BUG/MINOR: deviceatlas: fix double-checked locking race in checkinst

In da_haproxy_checkinst(), base[0] was checked before acquiring the
lock but not re-checked after. Another thread could have already
processed the reload between the initial check and the lock
acquisition, leading to a race condition.

This should be backported to lower branches.
