pgsql: Use correctly-sized buffer when zero-filling a WAL file.

Use correctly-sized buffer when zero-filling a WAL file.

I mixed up BLCKSZ and XLOG_BLCKSZ when I changed the way the buffer is
allocated a couple of weeks ago. With the default settings, they are both
8k, but they can be changed at compile-time.

Branch
------
REL8_4_STABLE
