Improve comment of pgstat_read_statsfile()

Browse Source 
The comment at the top of pgstat_read_statsfile() mentioned that the
stats are read from the on-disk file into the pgstats dshash.  This is
incorrect for fix-numbered stats as these are loaded directly into
shared memory.  This commit simplifies the comment to be more general.
