Cap wal_buffers to avoid a server crash when it's set very large.
It must be possible to multiply wal_buffers by XLOG_BLCKSZ without
overflowing int, or calculations in StartupXLOG will go badly wrong
and crash the server. Avoid that by imposing a maximum value on
wal_buffers. This will be just under 2GB, assuming the usual value
for XLOG_BLCKSZ.
