cris: avoid a write only variable

Compiling with GCC 4.6.0 20100925 produced a warning:
In file included from /src/qemu/target-cris/translate.c:3154:0:
/src/qemu/target-cris/translate_v10.c: In function 'dec10_prep_move_m':
/src/qemu/target-cris/translate_v10.c:111:22: error: variable 'rd' set but not used [-Werror=unused-but-set-variable]

Fix by deleting rd, adjust the only user.
