In insn_check_regs() we don't explicitly check whether
qemu_plugin_read_register() failed, which confuses Coverity into
thinking that sz can be -1 in the memcmp(). In fact the assertion
that sz == reg->last->len means this can't happen, but it's clearer
to both humans and Coverity if we explicitly assert that sz > 0, as
we already do in init_vcpu_register().
