dialog: Fix unsafe profile list iteration
The dialog->profile_links list _must always_ be walked after first
grabbing the dialog's lock, regardless of the current ref count.
Failing to do so may lead to invalid memory access, as the list
elements may get freed from other processes.
Many thanks to 46Labs for supporting this fix
(cherry picked from commit 5613922793b2b332354da30ab54b4e56f276bbda)
