patch 9.0.2117: [security] use-after-free in qf_free_items
Problem: [security] use-after-free in qf_free_items
Solution: only access qfpnext, if it hasn't been freed
Coverity discovered a possible use-after-free in qf_free_items. When
freeing the qfline items, we may access freed memory, when qfp ==
qfpnext.
So only access qfpnext, when it hasn't been freed.
