[patch] initialize some variables in m32c-tdep.c

[DJ Delorie <dj@redhat.com>]

Unless we have some magic "yes this is always initialized when used"
attribute, this is needed to build this file with -Werror.

	* m32c-tdep.c (m32c_decode_srcdest4): Initialize fields in sd
	that may not be initialized elsewhere.
	(m32c_decode_sd23): Likewise.
