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.
