kasan: simplify async check in end_report()
Currently, end_report() does not call trace_error_report_end() for bugs
detected in either async or asymm mode (when kasan_async_fault_possible()
returns true), as the address of the bad access might be unknown.
However, for asymm mode, the address is known for faults triggered by read
operations.
Instead of using kasan_async_fault_possible(), simply check that the addr
is not NULL when calling trace_error_report_end().
