Rick Macklem d4a11b3e3b nfscl: Fix CreateSession for an established ClientID
Commit 981ef32230b2 added optional use of the session
slots marked bad to recover a new session when all
slots are marked bad.  The recovery worked against
a FreeBSD NFSv4.1/4.2 server, but not a Linux one.
It turns out that it was a bug in the FreeBSD client
and not the Linux server.

This patch fixes the client so that DeleteSession
followed by CreateSession after receiving a
NFSERR_BADSESSION error reply works against the
Linux server (and conforms to the RFC).

This also implies that the FreeBSD NFSv4.1/4.2
server needs to be fixed in a future commit.
Without the fix, the FreeBSD server does a full
recovery, including creation of a new ClientID,
but since "intr" mounts were broken, this does
not result in a regression.

This patch only affects the case where a CreateSession
is done for an already confirmed ClientID, which was
not being done prior to commit 981ef32230b2.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
