To avoid compilation errors when -Werror=maybe-uninitialized is used,
replace 'case 3' by 'default'.
Otherwise we get:
../target/i386/ops_sse.h: In function ‘helper_vpermdq_ymm’:
../target/i386/ops_sse.h:2495:13: error: ‘r3’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
2495 | d->Q(3) = r3;
