mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!)
Problem:
This was causing the key to become "<token>--cur" instead of the expected
"<token>-cur". As the same key was used by the code to both set and get, it
still worked.
Rationale for change:
Although it worked, it's unintended, inconsistent and messy. It increases the
chances of future bugs due to the unexpected format.
Side-effects of change:
Existing '--cur' entries will not be checked after this change, and therefore
existing FAST clients will fail to authenticate until they attempt password
auth and obtain a new FAST token.
Existing '--cur' entries in storage will not be cleaned up by this commit, but
this is considered a minor issue, and okay for the relatively few FAST
deployments.
