ticket: 6734
subject: FAST negotiation could erroneously succeed
target_version: 1.8.2
tags: pullup
When FAST negotiation is performed against an older KDC
(rep->enc_part2->flags & TKT_FLG_ENC_PA_REP not set),
krb5int_fast_verify_nego did not set the value of *fast_avail, causing
stack garbage to be used in init_creds_step_reply. Initialize
*fast_avail at the beginning of the function per coding practices.
ticket: 6734
version_fixed: 1.8.2
