  fs/cifs: Fix resource leak (2021-05-04 11:53:15 -0500)

----------------------------------------------------------------
10 CIFS/SMB3 changesets (including two for stable):
- some important multichannel fixes
- support for handle leases (deferred close)
- shutdown support (which is also helpful since it enables multiple xfstests)
- enable negotiating stronger encryption by default (GCM256)
- improve wireshark debugging by allowing more options for root to
dump decryption keys

SambaXP and the SMB3 Plugfest test event are going on now so I am
expecting more patches over the next few days due to extra testing
(including more multichannel fixes).
