DBObjectMap: lock header_lock on sync()

Otherwise, we can race with another thread updating state.seq
resulting in the old, smaller value getting persisted.  If there
is a crash at that time, we will reuse a sequence number, resulting
in an inconsistent node tree and bug #9891.

Fixes: 9891
Backport: giant, firefly, dumpling
