clk: sandbox: don't check clk ID against 0
clk->id is unsigned, so it can't be < 0. Remove the check for that.
FWIW, this issue was introduced when the clock API converted e.g.
clk_get_rate()'s clock ID parameter from an int to an unsigned long
(with a struct clk), without removing this check.
Fixes: 135aa9500264 ("clk: convert API to match reset/mailbox style")
