handle following sequence of events:
- client releases a inode with i_max_size > 0. The release message
is queued. (is not sent to the auth MDS)
- a 'lookup' request reply from non-auth MDS returns the same inode.
- client opens the inode in write mode. The version of inode trace
in 'open' request reply is equal to the cached inode's version.
- client requests new max size. The MDS ignores the request because
it does not affect client's write range
