libssh2: kdb_callback: get the right struct pointer

Browse Source 
After the recent conn/data refactor in this source file, this function
was mistakenly still getting the old struct pointer which would lead to
crash on servers with keyboard-interactive auth enabled.

Follow-up to a304051620 (shipped in 7.75.0)

Reported-by: Christian Schmitz
Fixes #6691
Closes #6782
