Namjae Jeon 3898d8d685 ksmbd: not allow to open file if delelete on close bit is set 
[ Upstream commit f43328357d ]

Cthon test fail with the following error.

check for proper open/unlink operation
nfsjunk files before unlink:
  -rwxr-xr-x 1 root root 0  9월 25 11:03 ./nfs2y8Jm9
./nfs2y8Jm9 open; unlink ret = 0
nfsjunk files after unlink:
  -rwxr-xr-x 1 root root 0  9월 25 11:03 ./nfs2y8Jm9
data compare ok
nfsjunk files after close:
  ls: cannot access './nfs2y8Jm9': No such file or directory
special tests failed

Cthon expect to second unlink failure when file is already unlinked.
ksmbd can not allow to open file if flags of ksmbd inode is set with
S_DEL_ON_CLS flags.
