What I did
Removed access to variable causing the segfault while create_entry with attr_count 0
Why I did it
When the bulker create_entry was called with attr_count as 0, the swss log would access the attr_list and try to print the id. This was causing the orchagent crash:
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x000056230970734d in EntityBulker<_sai_nat_api_t>::create_entry (this=0x56230b31f988, object_status=0x56230b3e4a20, entry=, attr_count=0, attr_list=0x7ffcadbbbef0) at /usr/include/c++/8/bits/unordered_map.h:309
How I verified it
Verified orchagent does not segfault under this condition.
