disas/cris.c: Fix Coverity warning about unchecked NULL
Coverity (CID 1005689) warns that we don't check that spec_reg_info() returned non-NULL before dereferencing. Add the check, though as the comment notes this is a can't-really-happen case because the earlier constraint matching should have ruled out the "unknown reg" case.
