smb: client: fix atomic open with O_DIRECT & O_SYNC
commit 4a7d2729dc99437dbb880a64c47828c0d191b308 upstream.
When user application requests O_DIRECT|O_SYNC along with O_CREAT on
open(2), CREATE_NO_BUFFER and CREATE_WRITE_THROUGH bits were missed in
CREATE request when performing an atomic open, thus leading to
potentially data integrity issues.
Fix this by setting those missing bits in CREATE request when
O_DIRECT|O_SYNC has been specified in cifs_do_create().
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
