[PATCH 2/5] sim frv: Add a missing return value for frvbf_check_acc_range.

[John Baldwin <jhb@FreeBSD.org>]

Claim that the accumulator indices are out of range without raising an
exception if the CPU doesn't support media instructions.

sim/frv/ChangeLog:

	* traps.c (frvbf_check_acc_range): Add missing return value.
