Olivier Dugeon 4b753fd134 ospfd: protect call to get_edge() in ospf_te.c 
During fuzzing, Iggy Frankovic discovered that get_edge() function in ospf_te.c
could return null pointer, in particular when the link_id or advertised router
IP addresses are fuzzed. As the null pointer returned by get_edge() function is
not handlei by calling functions, this could cause ospfd crash.

This patch introduces new verification of returned pointer by get_edge()
function and stop the processing in case of null pointer. In addition, link ID
and advertiser router ID are validated before calling ls_find_edge_by_key() to
avoid the creation of a new edge with an invalid key.
