HAMMER VFS - Fix inconsistent atime updates on read()
* HAMMER's optimization of the read() path to improve concurrency broke
atime updates in the cache case. There was a big XXX comment in the
code about it.
* Fix the issue in a way that avoids acquiring the fs_token in the cache
case. If the ATIME flag is already set all we need to do is update
ip->ino_data.atime. If it is not set we have to get the fs_token and
go through the normal transaction.
