Change report header format from:

BUG: KASAN: use-after-free in unwind_get_return_address+0x28a/0x2c0 at addr ffff880069437950
Read of size 8 by task insmod/3925

to:

BUG: KASAN: use-after-free in unwind_get_return_address+0x28a/0x2c0
Read of size 8 at addr ffff880069437950 by task insmod/3925

The exact access address is not usually important, so move it to the
second line. This also makes the header look visually balanced.
