pgsql: Fix erroneous choices of segNo variables

Fix erroneous choices of segNo variables

Commit dfda6eba (which changed segment numbers to use a single 64 bit
variable instead of log/seg) introduced a couple of bogus choices of
exactly which log segment number variable to use in each case.

This is currently pretty harmless; in one place, the bogus number was
only being used in an error message for a pretty unlikely condition
(failure to fsync a WAL segment file). In the other, it was using a
global variable instead of the local variable; but all callsites were
passing the value of the global variable anyway.

No need to backpatch because that commit is not on earlier branches.
