If a non SA aware component has configured a healthcheck command in the 
comptype but has not configured a healthcheck object this happens when the SU 
is locked.

Reason is a combination of bad error handling in amfnd and not so strict error 
handling in leap double linked list. avnd_comp_hc_rec_add() fails and calls to 
unlink the rec from the list. Since the rec has never been added this just 
decrements the n_nodes counter to -1. This check later fails as can be seen in 
the assert.
