subject: Fix KDB iteration when callback does write calls
target_version: 1.10.1
tags: pullup

kdb_db2's ctx_iterate makes an convenience alias to dbc->db in order
to call more invoke call the DB's seq method. This alias may become
invalidated if the callback writes to the DB, since ctx_lock() may
re-open the DB in order to acquire a write lock. Fix the bug by
getting rid of the convenience alias.

Most KDB iteration operations in the code base do not write to the DB,
but kdb5_util update_princ_encryption does.
