kasan: drop addr check from describe_object_addr
Patch series "kasan: report clean-ups and improvements".
A number of clean-up patches for KASAN reporting code. Most are
non-functional and only improve readability.
This patch (of 22):
describe_object_addr() used to be called with NULL addr in the early days
of KASAN. This no longer happens, so drop the check.
