I think it actually fixes xprt_switch_find_current_entry_offline().

Looking closely at _xprt_switch_find_current_entry:

		if (found && ((find_active && xprt_is_active(pos)) ||
			      (!find_active && xprt_is_active(pos))))

and comparing with similar code in xprt_switch_find_next_entry:

		if (found && ((check_active && xprt_is_active(pos)) ||
			      (!check_active && !xprt_is_active(pos))))

There is a difference in the number of '!'.  I suspect the former is
wrong.
If the former is correct, then "find_active" is irrelevant.
