[LU-7604] Issues with Kerberos when flushing context or destroying tickets

Description

When running sanity-krb5.sh test script, several errors are due to a problem with handling of context flush or ticket destroy by Lustre code.

It appears that the behavior of request_key kernel function has changed from RHEL6/CentOS6 to RHEL7/CentOS7. With recent versions, a key is no longer returned if it is not usable (like revoked). This new behavior does not please Lustre expectations, and lead to the impossibility to access the Lustre file system.

Of course Lustre code has to be changed to comply with fixed request_key kernel function.
I will submit a patch to address this problem.

Sebastien.
