[PATCH v2 2/3] hfs: correct superblock flags

[Yangtao Li]

We don't support atime updates of any kind,
because hfs actually does not have atime.

   dirCrDat:      LongInt;    {date and time of creation}
   dirMdDat:      LongInt;    {date and time of last modification}
   dirBkDat:      LongInt;    {date and time of last backup}

   filCrDat:      LongInt;    {date and time of creation}
   filMdDat:      LongInt;    {date and time of last modification}
   filBkDat:      LongInt;    {date and time of last backup}

W/O patch(xfstest generic/003):

 +ERROR: access time has changed for file1 after remount
 +ERROR: access time has changed after modifying file1
 +ERROR: change time has not been updated after changing file1
 +ERROR: access time has changed for file in read-only filesystem

W/ patch(xfstest generic/003):

 +ERROR: access time has not been updated after accessing file1 first time
 +ERROR: access time has not been updated after accessing file2
 +ERROR: access time has changed after modifying file1
 +ERROR: change time has not been updated after changing file1
 +ERROR: access time has not been updated after accessing file3 second time
