YJIT: Fix reference update for `Invariants::no_ep_escape_iseqs`

Previously, the update was done in the ISEQ callback. That effectively
never updated anything because the callback itself is given an intact
reference, so it could update its content, and `rb_gc_location(iseq)`
never returned a new address. Update the whole table once in the YJIT
root instead.
