RISC-V SMP support is not yet implemented, but smp_send_event_check_mask()

Provide a temporary stub implementation that asserts the mask only targets
CPU0.
cpumask_subset() is used instead of cpumask_equal() because some callers
(e.g. cpumask_raise_softirq() or cpu_raise_softirq_batch_finish()) may
legitimately pass an empty mask, which would otherwise cause false
failures.
The BUG_ON() ensures that attempts to use this function with multiple CPUs
are caught early once SMP support is introduced.

Thanks.
Looks like this is independent of earlier patches in the series, and hence
could go in right away? Please confirm.
I confirm that it is independent and could go right away. I, also, checked
locally compilation of this patch on top of current staging and it is fine.
