Обсуждение: Small patch modifying variable name to reflect the logic involved

Hi All,

Please find a small patch to improve code readability by modifying
variable name to reflect the logic involved - finding diff between end
and start time of WAL sync.

-    INSTR_TIME_ACCUM_DIFF(PendingWalStats.wal_sync_time, duration, start);
+    INSTR_TIME_SET_CURRENT(end);
+    INSTR_TIME_ACCUM_DIFF(PendingWalStats.wal_sync_time, end, start);

Agreed, the duration is the result of the INSTR_TIME_ACCUM_DIFF calculation,
not what's stored in the instr_time variable.

And done, with a small fixup to handle another occurrence in the same file.
