frontends/va: Fix *num_entrypoints check. 

Fix defect reported by Coverity Scan.

Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking num_entrypoints suggests that it
may be null, but it has already been dereferenced on all paths
leading to the check.

Fixes: 5bcaa1b9e9 ("st/va: add encode entrypoint v2")
