Subject: smb3: fix Open files on server counter going negative
From: Steve French <stfrench@xxxxxxxxxxxxx>
commit 28e0947651ce6a2200b9a7eceb93282e97d7e51a upstream.
We were decrementing the count of open files on server twice
for the case where we were closing cached directories.
Fixes: 8e843bf38f7b ("cifs: return a single-use cfid if we did not get a lease")
