Subject: [PATCH] extensions/vtab: fix i32 being passed as i64 across FFI
 boundary

as nilskch points out in #1807, Rust 1.88.0 is stricter about
alignment.

because rust integers default to `i32`, we were casting a pointer
to an `i32` as a pointer to an `i64` causing a panic when dereferenced
due to misalignment as rust expects it to be 8 byte aligned.
