`V3SchedTiming` currently assumes that if a fork still exists, it must
have statements within it (otherwise it would have been deleted by
`V3Timing`). However, in a case like this:
```
module t;
reg a;
initial fork a = 1; join
endmodule
```
the assignment in the fork is optimized out by `V3Dead` after
`V3Timing`. This leads to `V3SchedTiming` accessing fork's `stmtsp`
pointer, which at this point is null. This patch addresses that issue.
