Peter Maydell 3977ee5d7a target-arm: Correct "preferred return address" for cpreg access exceptions
The architecture defines that when taking an exception trying to
access a coprocessor register, the "preferred return address" for
the exception is the address of the instruction that caused the
exception. Correct an off-by-4 error which meant we were returning
the address after the instruction for traps which happened because
of a failure of a runtime access-check function on an AArch32
register. (Traps caused by translate-time checkable permissions
failures had the correct address, as did traps on AArch64 registers.)
