I wrote "while not in standby mode, we don't need to avoid retry the
entire record" but that doesn't mean the inversion "while in standby
mode, we need to do avoid that". In the first place retry doesn't
happen while not in standby mode. I don't come up with a nice
phrasing but something like this works?
Note that we don't do this while not in standby mode because this is
required only to avoid retrying this entire record for an invalid page
header while in standby mode. Instead, ReadPageInternal() is
responsible for validating the page header in that case.
