cifs: if deferred close is disabled then close files immediately

Browse source 
[ Upstream commit df9d70c186 ]

If defer close timeout value is set to 0, then there is no
need to include files in the deferred close list and utilize
the delayed worker for closing. Instead, we can close them
immediately.
