Currently touch_atime and file_update_time directly update a/c/mtime

bad for some more complex filesystems that have various different types
of dirtying an inode and/or need to store the data in another place
for example for a buffer to be logged.
This patch changes touch_atime and file_update_time to not update the
inode directly but rather call through ->setattr into the filessystem.
This patch would make our (UBIFS develpers') life easier, thank you!
Could we go a further and allow the file-system returning error if it
for some reasons cannot change the time? For example, the FS could
return -EIO or -ENOSPC up and VFS would have to free resources and
propagate this error to user-space. Is this possible?
