Hu Weiwen 194f59391d ceph: don't truncate file in atomic_open 
commit 7cb9994754f8a36ae9e5ec4597c5c4c2d6c03832 upstream.

Clear O_TRUNC from the flags sent in the MDS create request.

`atomic_open' is called before permission check. We should not do any
modification to the file here. The caller will do the truncation
afterward.
