cifs: wait for writeback to complete in cifs_flush
The f_op->flush operation is the last chance to return a writeback
related error when closing a file. Ensure that we don't miss reporting
any errors by waiting for writeback to complete in cifs_flush before
proceeding.
There's no reason to do this when the file isn't open for write
however.
