Zhang Xiaoxu 860efae127 cifs: Fix memory leak on the deferred close 
commit ca08d0eac0 upstream.

xfstests on smb21 report kmemleak as below:

  unreferenced object 0xffff8881767d6200 (size 64):
    comm "xfs_io", pid 1284, jiffies 4294777434 (age 20.789s)
    hex dump (first 32 bytes):
      80 5a d0 11 81 88 ff ff 78 8a aa 63 81 88 ff ff  .Z......x..c....
      00 71 99 76 81 88 ff ff 00 00 00 00 00 00 00 00  .q.v............

      [<00000000102e8a0b>] entry_SYSCALL_64_after_hwframe+0x46/0xb0

When cancel the deferred close work, we should also cleanup the struct
cifs_deferred_close.

Fixes: 9e992755be ("cifs: Call close synchronously during unlink/rename/lease break.")
Fixes: e3fc065682 ("cifs: Deferred close performance improvements")
