target/arm: Fix outdated comment about exception exit

Browse source 
When we switched our handling of exception exit to detect
the magic addresses at translate time rather than via
a do_unassigned_access hook, we forgot to update a
comment; correct the omission.

Backports commit 9d17da4b68a05fc78daa47f0f3d914eea5d802ea from qemu
