pgsql: Fix thinko when bumping on temporary directories inpg_verify_ch

Fix thinko when bumping on temporary directories in pg_verify_checksums

This fixes an oversight from 5c99513.  This has no actual consequence as
PG_TEMP_FILE_PREFIX and PG_TEMP_FILES_DIR have the same value so when
bumping on a temporary path the directory scan was still moving on to
the next entry instead of skipping the rest of the scan, but let's keep
the logic correct.
