Testing:

CONFIG_NFS_V4_1

and the new INJECT_ERROR_CTHON test where NFS4ERR_BADSESSION was returned
every 50th SEQUENCE operation durring a Connectathon basic test run. This passed
with the session being reset 390 times from a variety of client compounds
(READ/WRITE/COMMIT/OPEN/CLOSE/ to name a few).
