kasan: rework function arguments in report.c

Pass a pointer to kasan_report_info to describe_object() and
describe_object_stacks(), instead of passing the structure's fields.

The untagged pointer and the tag are still passed as separate arguments to
some of the functions to avoid duplicating the untagging logic.

This is preparatory change for the next patch.
