modules_k/dialog: Improve error handling during dialog creation.
- Set current dialog only after all other setup work succeeded.
(Eliminates call to profile_cleanup() and guarantees that dialog
profiling does not yield to segfault if dialog creation fails
for certain reasons.)
- During error handling, refrain from decrementing the reference
counter for dialog linking if this is a spiraled request
(because positive spiral detection skips the linkage code path).
(cherry picked from commit 71dd754818d8c3ec304298f1002a45889c2da0aa)
