nfsd: nfsd4_setclientid_confirm mistakenly expires confirmed client.
commit ab451ea952fe9d7afefae55ddb28943a148247fe upstream.
From RFC 7530 Section 16.34.5:
o The server has not recorded an unconfirmed { v, x, c, *, * } and
has recorded a confirmed { v, x, c, *, s }. If the principals of
the record and of SETCLIENTID_CONFIRM do not match, the server
returns NFS4ERR_CLID_INUSE without removing any relevant leased
client state, and without changing recorded callback and
callback_ident values for client { x }.
The current code intends to do what the spec describes above but
it forgot to set 'old' to NULL resulting to the confirmed client
to be expired.
Fixes: 2b63482185e6 ("nfsd: fix clid_inuse on mount with security change")
